Answer 2

Answer:

10:38 am

Step-by-step explanation:

You can use a number line or clock to find the start time

x = 0:15 min - 0:37 min x = -0:22 min

y = 60 min - 22 min y = 38 min

Time = 12:38

1st, subtract the minutes from the end time. If the value is negative, it means that the time goes back into the previous hour.

Subtract from 60 minutes. Time after going back 37 minutes.

Next, subtract the hours from the time. 11:38 am 10:38 am and 10:38

Next, subtract the hours from the time. Going back 1 hour. Going back 2 hour.

Start time is 10:38
