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

5 km/h

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

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:
