Explanation:

Step1: Identify the bus direction and Andrea's boarding time

Andrea is catching the bus at Downtown Liberty Avenue (to go home to Springdale), so we look at the "To Tarentum - Natrona Heights" schedule (since Springdale is on the way to Tarentum - Natrona Heights from Downtown). She wants to catch the bus at 5:15. We find the row where the Downtown Liberty Ave (at Gateway #4) time is 5:15 (in the "To Tarentum - Natrona Heights" schedule, the first column for Downtown Liberty Ave at Gateway #4 has times, and we look for 5:15).

Step2: Find the corresponding Springdale time

In the "To Tarentum - Natrona Heights" schedule, the row with Downtown Liberty Ave at Gateway #4 time 5:15: we follow that row across to the Springdale column. Looking at the table, for the row starting with 5:15 (Downtown Liberty Ave at Gateway #4), the Springdale (Pittsburgh St past Colfax St) time is 6:03? Wait, no, wait. Wait, Andrea is at Downtown Liberty Avenue (bus stop for going to Tarentum - Natrona Heights) at 5:15? Wait, no, wait the first schedule is "To Downtown Pittsburgh" (going towards Downtown) and the second is "To Tarentum - Natrona Heights" (going away from Downtown, towards Springdale and beyond). Andrea is at Downtown Liberty Avenue (near her work) to go home to Springdale, so she needs the "To Tarentum - Natrona Heights" bus. Wait, no, wait: her work is at Downtown Liberty Avenue bus stop, and she wants to go to Springdale. So she is taking the bus from Downtown (Liberty Ave) to Springdale, so the "To Tarentum - Natrona Heights" schedule. Let's check the "To Tarentum - Natrona Heights" schedule: the column for Springdale (Pittsburgh St past Colfax St). Let's find the bus that departs Downtown Liberty Ave at Gateway #4 at 5:15 (the row where Downtown Liberty Ave at Gateway #4 is 5:15). Then, looking at the Springdale column (Pittsburgh St past Colfax St) in that row: let's list the rows for "To Tarentum - Natrona Heights":

Row 1: 3:30, 3:39, 3:45, 3:49, 4:02, 4:11, 4:17, 4:20, 4:28, 4:34, 4:39, 4:41, 4:48, 4:50

Row 2: 3:55, 4:04, 4:10, 4:14, 4:27, 4:36, 4:42, 4:45, 4:53, 4:59, 5:04, 5:06, 5:13, 5:15

Row 3: 4:10, 4:19, 4:25, 4:29, 4:42, 4:51, 4:57, 5:00, 5:08, 5:14, 5:19, 5:21, 5:28, 5:30

Row 4: 4:25, 4:34, 4:40, 4:44, 4:57, 5:06, 5:12, 5:15, 5:23, 5:29, 5:34, 5:36, 5:43, 5:45

Row 5: 4:40, 4:49, 4:55, 4:59, 5:12, 5:21, 5:27, 5:30, 5:38, 5:44, 5:49, 5:51, 5:58, 6:00

Row 6: 5:00, 5:09, 5:15, 5:19, 5:30, 5:39, 5:45, 5:48, 5:56, 6:02, 6:07, 6:09, 6:16, 6:18

Row 7: 5:15, 5:24, 5:30, 5:34, 5:45, 5:54, 6:00, 6:03, 6:11, 6:17, 6:22, 6:24, 6:31, 6:33

Row 8: 5:35, 5:44, 5:50, 5:54, 6:05, 6:14, 6:20, 6:23, 6:31, 6:37, 6:42, 6:44, 6:51, 6:53

Row 9: 5:55, 6:04, 6:10, 6:14, 6:25, 6:34, 6:40, 6:43, 6:51, 6:57, 7:02, 7:04, 7:11, 7:13

Wait, the Downtown Liberty Ave at Gateway #4 column (first column) has times: 3:30, 3:55, 4:10, 4:25, 4:40, 5:00, 5:15, 5:35, 5:55. So the row with 5:15 in the first column (Downtown Liberty Ave at Gateway #4) is row 7 (indexing from top: row 1: 3:30, row 2: 3:55, row 3: 4:10, row 4: 4:25, row 5: 4:40, row 6: 5:00, row 7: 5:15, row 8: 5:35, row 9: 5:55). Now, the Springdale column (Pittsburgh St past Colfax St) is the 8th column (counting from left: 1: Downtown Liberty, 2: Downtown Penn Station, 3: East Liberty, 4: Larimer, 5: RIDC Park, 6: Harmar, 7: Cheswick, 8: Springdale, 9: Creighton, 10: Tarentum, 11: Brackenridge, 12: Natrona Heights, 13: Harrison, 14: Harrison). So in row 7 (5:15 in column 1), column 8 (Springdale) has 6:03. Wait, but let's check the other schedule: the "To Downtown Pittsburgh" schedule (going towards Downtown) has Springdale times, but Andrea is going away from Downtown, so the "To Tarentum - Natrona Heights" is correct. Wait, maybe I made a mistake. Wait, Andrea is at Downtown Liberty Avenue (bus stop) to go to Springdale, so she is taking the bus that is heading to Tarentum - Natrona Heights, so the "To Tarentum - Natrona Heights" schedule. Let's confirm the bus stop names: in the "To Downtown Pittsburgh" schedule, the last stop is Downtown Liberty Ave at Gateway #4 (going towards Downtown), and in the "To Tarentum - Natrona Heights" schedule, the first stop is Downtown Liberty Ave at Gateway #4 (going away from Downtown). So Andrea is at the first stop of the "To Tarentum - Natrona Heights" bus (Downtown Liberty Ave at Gateway #4) at 5:15, and she wants to get off at Springdale. So following that row, the Springdale time is 6:03? Wait, but let's check the "To Downtown Pittsburgh" schedule: maybe Andrea is taking the bus towards Downtown, but no, her home is near Springdale, which is away from Downtown. Wait, no, the first schedule is "To Downtown Pittsburgh" (buses coming from Tarentum - Natrona Heights, Springdale, etc., going to Downtown). So Andrea is at Downtown (her work) and wants to go home to Springdale, so she needs to take the bus that is leaving Downtown (going to Tarentum - Natrona Heights), which is the "To Tarentum - Natrona Heights" schedule. So in that schedule, the bus departs Downtown Liberty Ave at Gateway #4 at 5:15, and arrives at Springdale (Pittsburgh St past Colfax St) at 6:03? Wait, but let's check the "To Downtown Pittsburgh" schedule: if Andrea was taking a bus towards Downtown, but she is going home, so away from Downtown. Wait, maybe I mixed up the directions. Let's re-express:

- "To Downtown Pittsburgh" (inbound): buses start from Harrison, Tarentum, etc., and end at Downtown Liberty Ave (going towards Downtown). So these are buses coming into Downtown.

- "To Tarentum - Natrona Heights" (outbound): buses start from Downtown Liberty Ave and go to Harrison, Tarentum, etc. (going away from Downtown).

So Andrea is at Downtown Liberty Ave (her work) and wants to go to Springdale (home), so she takes the outbound bus (To Tarentum - Natrona Heights) that departs Downtown Liberty Ave at 5:15. Then, looking at the Springdale stop (Pittsburgh St past Colfax St) in that outbound bus's schedule, the time is 6:03. Wait, but let's check the inbound schedule (To Downtown Pittsburgh) for Springdale: in the inbound schedule, Springdale (Pittsburgh St past Colfax St) has times like 5:42, 6:02, 6:22, etc. But those are buses coming into Downtown, so Andrea can't take those. So the correct schedule is the outbound (To Tarentum - Natrona Heights), and the time at Springdale is 6:03. Wait, but let's check the row again. In the outbound schedule, row with Downtown Liberty Ave at Gateway #4 time 5:15:

Downtown Liberty Ave at Gateway #4: 5:15

Downtown Penn Station Stop B: 5:24

East Liberty East Liberty Station Stop B: 5:30

Larimer Fifth Ave at Frankstown Ave: 5:34

RIDC Park Hwy 28 Expwy Ramp at Gamma Dr: 5:45

Harmar Alpha Dr at Harmar Park-and-Ride: 5:54

Cheswick Pittsburgh St at Highland Ave: 6:00

Springdale Pittsburgh St past Colfax St: 6:03

Yes, that's correct. So the bus departs Downtown Liberty Ave at 5:15 (outbound) and arrives at Springdale at 6:03. Wait, but let's confirm with the inbound schedule: in the inbound schedule (To Downtown Pittsburgh), the Springdale time for the bus that departs Harrison at 5:08 arrives at Springdale at 5:42. But Andrea is at Downtown, so she needs the outbound bus. So the correct arrival time at Springdale is 6:03? Wait, no, maybe I made a mistake in the row. Wait, the outbound schedule's rows: let's list the times for Downtown Liberty Ave at Gateway #4 (first column):

1. 3:30

2. 3:55

3. 4:10

4. 4:25

5. 4:40

6. 5:00

7. 5:15

8. 5:35

9. 5:55

So row 7 is 5:15. Then, the Springdale column (8th column) in row 7 is 6:03. Yes, that seems right.

Answer:

6:03
