Answer:
25 minutes
Explanation:
Note that Art Class is supposed to end at 3:30, but you are let out late 5 minutes. This means that the time you were allowed out is 3:35.
You're mom arrived at 3:10. Subtract the minutes:
35 - 10 = 25
You're mom had to wait 25 minutes, from 3:10 pm (the time she arrived) to 3:35 pm.
