Question

A motorist traveling on a straight stretch of open highway sets his cruise control at 90.0 km/h how far will he travel in 15 minutes

Answer 1

The distance covered by the motorist is 22.5 km

What is the distance?

The distance is a physical quantity that measures the space or area covered by an object between two points.

From the parameters given:

• The speed of an object = 90.0 km/h
• The time used to travel the speed = 15 minutes

Using the relation for speed:

• Speed = distance/time

Let's make the distance the subject of the formula, we have:

• Distance = speed × time

Distance = 90.0 km/h × 15 minutes

Recall that:

• 60 minutes = 1 hour
• 15 minutes = 0.25 hour

Thus,  the distance = 90.0 km/h × 0.25 hour

Distance = 22.5 km
