Question

A car travel 30 1/2 in 2/3 of an hour. What is the average speed,in miles per hour, of the car

Answer 1

45.3 miles/h

Step-by-step explanation:

let 'x' be the speed of the car.

60 × 2/3 = 120/3 = 40

30 × 1/5 = 151/5

151/5 /40 = x / 60

151 / 200 = x / 60

=> x = (151×60) / 200

=> x = 45.3
