Question

A driver spent 45minutes to cover a distance of 120km. what is the speed of the driver in km per hour.

Answer 1

• The speed is 160 km /h

Explanation:

A driver spent 45minutes to cover a distance of 120km

Convert minutes to hour

• 45 min = 45 /60 hr = 3/4 hr

Use the distance equation

• d = ts

Find the speed

• s = d/t

Substitute the distance and time value and find the value of speed

• s = 120 / (3/4) = 120 * 4/3 = 160 km /h
