Question

Carl runs 10km in 2 hours. How fast does he run the race

Answer 1

5 km/h

Step-by-step explanation:

The speed of an object is a scalar quantity telling us "how fast" an object is moving, regardless of its direction of motion.

The speed of an object is given by

`v=(d)/(t)`

where

d is the distance covered by the object, which is the total length of the path covered

t is the time taken

In this problem we have:

d = 10 km is the distance covered by Carl

t = 2 h is the time taken

So, the speed of Carl is:

`v=(10)/(2)=5 km/h`
