# How Many Minutes?

Algebra Level 1

I ran for 5 laps with a total of exactly 7 minutes and 30 seconds; each lap equals 400 meters. My father wanted to know how fast I ran on average in one lap. So my mother calculated $7.5 \div 5 = 1.5,$ and she concluded that I ran for 1 minute and 50 seconds in each lap. Is she correct?
