Question

nora left her house and drove to the store. she stopped and went inside. from there, she drove in the same direction until she got to the bank. she stopped and went inside the bank. then she drove home. the graph below shows the number of blocks away from home nora is ( x ) minutes after she left her house, until she got back home.

graph: ( y )-axis: distance (blocks from home), ( x )-axis: time elapsed (minutes). plot shows: from (0,0) up to (2,8), horizontal to (6,8), up to (10,16), horizontal to (17,16), down to (23,0).

how long was nora in the bank?

Explanation:

Step1: Identify the time interval when Nora was in the bank.

Looking at the graph, the horizontal segment (where distance from home is constant) represents the time Nora was at the bank. The start time of this segment is at \( x = 10 \) minutes and the end time is at \( x = 17 \) minutes.

Step2: Calculate the duration.

To find the time Nora was in the bank, we subtract the start time from the end time. So, \( 17 - 10 = 7 \) minutes.

Answer:

7 minutes
