Step-by-step explanation:
Time taken to solve 1 math problem - 10 minutes
Time to end the solves - 10:30
No. of solves - 15
Time to start - 10*15 = 150 minute( convert minute to hours)
=150 minutes - 60 minutes
= 90 minutes
=90 minutes - 60 minutes
= 30 minutes
= from the beggining when we started converting
we already
subtracted two times 60 so we have 2 hours
= 2 hours + 30 minutes
= 2 hours 30 minutes
= 8:00 am + 2 hours 30 minutes = 10:30
