A runner completes one lap of a 200 meter circular track in 50 seconds. What is the average speed of the runner?
4 meter per second
To find the average speed of the runner, we can use the formula for average speed, which is given by:
\(\text{Average Speed} = \frac{\text{Total Distance}}{\text{Total Time}}\)
In this case:
- Total Distance covered by the runner is one lap of the circular track, which is 200 meters.
- Total Time taken to complete one lap is 50 seconds.
Using the formula:
\(\text{Average Speed} = \frac{200 \, \text{meters}}{50 \, \text{seconds}}\)
Calculating the above expression:
\(= \frac{200}{50} = 4 \, \text{meters per second}\)
Therefore, the average speed of the runner is 4 meters per second.
Let's evaluate the options given:
- 4.5 meters per second - Incorrect, as it is higher than the calculated average speed.
- 3 meters per second - Incorrect, as it is lower than the calculated average speed.
- 3.5 meters per second - Incorrect, as it is lower than the calculated average speed.
- 4 meters per second - Correct answer as it matches the calculated average speed.
Thus, the correct answer is 4 meters per second.
