Question

What is his speed?A. 80 m/minB. 0.01 m/minC. 2000 m/min

Answer 1

To find his speed, we just have to divide d/v because that's the definition of speed.

`v=(d)/(t)`

Where d = 400 meters and t = 5 minutes.

`\begin{gathered} v=(400m)/(5\min ) \\ v=80\cdot(m)/(\min ) \end{gathered}`

Therefore, the answer is A. 80 m/min.
