Answer:
1 hour 37 minutes
Explanation:
From the image attached, we can see the start and end time represented by the clock. To calculate the length of time that Maria and her friends rode, we just have to subtract the start time from the end time.
From the end time clock, we can see that the end time is 2:24, while from the start time clock, we can see that the start time is 12:47. Hence, the length of time they rode is:
Length of time for bike ride = 2:24 - 12:47 = 1 hour 37 minutes
