A cross country runner runs 8 km in 2 minutes. What is his speed?

oee [108]

The speed of the cross country runner is equal to 4 km/min.

Given the following data:

Distance = 8 km.

Time = 2 minutes.

To determine the speed of the cross country runner:

Speed can be defined as the distance covered by an individual per unit time and it can be measured in kilometer per minutes (km/min).

Mathematically, speed is given by the formula;

$Speed = \frac{distance}{time}$

Substituting the given parameters into the formula, we have;

$Speed = \frac{8}{2}$

Speed = 4 km/min.
