Question

HELP PLEASE ASAP. A runner travels 400 meters in 80 seconds, what is the runner’s average speed?

Answer 1

Answer:

v = 5 m/s

Explanation:

Given that,

The distance covered by a runner, d = 400 m

Time, t = 80 sec

We need to find the runner's average speed. It is equal to total distance covered divided by time taken. It can be given by:

$v=\dfrac{d}{t}\\\\v=\dfrac{400\ m}{80\ s}\\\\v=5\ m/s$

So, the runner’s average speed is 5 m/s.
