Question

An olympic gold medalist from Moscow runs one time around the 400-meter track in 36seconds.What is her average speed?Answer:m/s

Answer 1

We are given the following information.

Distance covered = 400 m

TIme taken = 36 s

We are asked to find the average speed.

Recall that the average speed is given by

`s=(d)/(t)`

Where d is the distance traveled and t is the time.

`\begin{gathered} s=(400)/(36) \\ s=11.11\;(m)/(s) \end{gathered}`

The average speed is 11.11 m/s
