Question

how long did the temperature hold steady for?
answer attempt 2 out of 2
□ hours

Explanation:

Step1: Identify steady temperature segment

The graph has a horizontal segment (temperature holds steady) between 12 Noon (12 pm) and 6 pm.

Step2: Calculate time duration

Time from 12 pm to 6 pm is \( 6 - 0 = 6 \)? Wait, no. Wait, 12 pm to 6 pm: the difference in hours is \( 6 - 0 \)? Wait, no, 12 pm to 6 pm is 6 hours? Wait, no, let's check the x - axis. The horizontal part is from 12 (noon) to 6 (pm). So the time elapsed is \( 6 - 0 \)? Wait, no, the x - axis labels: 6 am, 12 Noon, 6 pm, 12 Midnight. The horizontal segment is between 12 Noon and 6 pm. The number of hours between 12 pm and 6 pm is \( 6 - 0 \)? Wait, no, 12 pm to 6 pm is 6 hours? Wait, no, 12 to 6 is 6 hours? Wait, no, 12 (noon) to 6 pm: 6 - 0? Wait, no, the time between 12 and 6 on the x - axis (where 12 is noon and 6 is pm) is 6 hours? Wait, no, let's see the horizontal line: the start at 12 (noon) and end at 6 pm. So the duration is \( 6 - 0 \)? Wait, no, 12 to 6 is 6 hours? Wait, no, 12 pm to 6 pm is 6 hours. Wait, but let's check the graph's x - axis intervals. From 6 am to 12 noon is 6 hours, 12 noon to 6 pm is 6 hours, 6 pm to 12 midnight is 6 hours. The horizontal segment is from 12 noon to 6 pm, so the length is 6 hours? Wait, no, wait the horizontal part: the first point of the horizontal segment is at 12 noon, the second at 6 pm. So the time between them is \( 6 - 0 \)? Wait, no, 12 to 6 is 6 hours. So the temperature held steady for 6 hours? Wait, no, wait maybe I made a mistake. Wait, 12 noon to 6 pm: the difference in hours is 6. So the duration is 6 hours? Wait, no, let's count the hours. From 12 (noon) to 1 pm is 1 hour, 1 to 2 is 1, ..., up to 6 pm: that's 6 hours. So the temperature held steady for 6 hours? Wait, no, wait the graph: the horizontal line is from 12 (noon) to 6 pm. So the time elapsed is 6 hours.
