Question

A car travels a distance of 145 miles in a time of 2.4 hours.

What is its average speed rounded to 1dp?

Answer 1

60.4miles/hr

Explanation:

Given parameters:

Distance covered by the car = 145miles

Time taken = 2.4hrs

Unknown:

Average speed of the car = ?

Solution:

Average speed is the rate of change of distance with time;

Average speed =
`(distance)/(time)`

Input the parameters and solve;

Average speed =
`(145)/(2.4)` = 60.4miles/hr
