Stephanie ran four laps around the school track in 7min and 30 sec how many sec per lap is that

tester [92]

Since each min is 60 seconds you multiply 60 by the number of minutes which is 7 and you get 420:

60x7=420 Then you add 30 seconds equaling 450 seconds total

Then you divide 450 by 4 since she ran 4 laps.

So, Stephanie ran 112.5 seconds per lap
