Question

A cyclist travels at an average speed of 8 km/h over a distance of 32 km. How many hours does it take him?

Answer 1

4 hours.

Explanation:

Well we can simply divide 32 by 8 and we get 4 hours:

32 miles ÷ 8 miles = 4 hours

It takes the cyclist 4 hours.

Answer 2

4 hours

Explanation:

As every speed limit sign tells you, ...

speed = miles/hours

Solving for time and using generic distance units, we get ...

time = distance/speed

Filling in the given values, we have ...

time = 32 km/(8 km/h) = (32/8) h = 4 h

It takes the cyclist 4 hours to travel 32 km.
