# A runner taking part in the 200m dash must run around the end of a track at what time if he is running at an average speed 20 meters/sec.

We will use the concept of speed, distance, and time in order to find the time taken by the runner.

## Answer: The runner will take 10 seconds in order to run 200m around the end of the track if he is running at an average speed of 20 meters/sec.

Let us see how we will use the concept of speed, distance, and time in order to find the time taken by the runner.

**Explanation:**

Given: Distance = 200m, Speed = 20m/s

We know that the relationship between distance, speed, and time is given by

Distance = Speed × Time

Hence, using the time formula,

Time = Distance / Speed

Now substituting the values of distance and speed we will get the required time.

Time = 200 / 20 = 10 s

### Hence, the runner will take 10 seconds to run a 200m dash.
