A runner runs at an average speed of 9 m/s for 20 seconds
How far did the runner run in metres?​

The answer would be 180 meters.

Step-by-step explanation:

We are told the runner runs at 9 m/s for 20 seconds.

Since they run 9 meters per second, all we have to do is multiply 9 by 20, which will give us 180 meters.

9 x 20 = 180
