Question

A car travels at 30 1/5 miles in 2/3 of an hour. What is the average speed in miles per hour of the car

Answer 1

Adverage of 20 mph

30 1/5 = 30.2

2/3 = .6667

30.2 x .6667 = 20.13

Answer 2

45.3 miles/hour

Explanation:

the information we have is:

distance:

`d=30(1)/(5)miles=30.2miles`

time:

`t=(2)/(3) hour`

the formula for the average speed is:

`v=(distance)/(time) =(d)/(t)`

substituting all the known values we get:

`v=(30.2miles)/(2/3hour) =(3(30.2miles))/(2hour)= 45.3miles/hour`

the average speed in miles per hour is: 45.3
