when you see per think fractions
15.2 miles per hour = 15.2 miles / 1 hour
since this is a fraction, Units can cancel just like numbers
To cancel miles and be left with hours rearrange the fraction
1 hour / 15.2 miles
then multiply by 72 miles

the miles cancel and youre left with hours!
so youd write and solve 72 / 15.2
2 1/2 feet can be written as 2.5 feet.
Divide the total distance by the distance per second:
15.6 feet / 2.5 feet per second = 6.24 seconds.
