Question

A car travels 30 1/5 miles in 3/4 of an hour.What is the average speed in miles per hour of the car

Answer 1

Divide miles driving by time.

Rewrite miles as improper fraction:

30 1/5 = 151/5

151/5 / 3/4

When dividing fractions change to multiplication and flip the second fraction over:

151/5 x 4/3 = 604/15 = 40 4/15 miles per hour
