So first we need to figure out the two times shown. Then we can figure out the amount of time that has elapsed between the two.
Clock #1 = 2:13
Clock #2 = 8:37
Now that we know the time, we just have to find the difference between the two.
2:13 + 6 hours = 8:13
8:13 + 24 minutes = 8:37
The time that passed from the first clock to the second clock is:
6 hours and 24 minutes
Hope that helps!!
