Question

A sprinter runs 100 meters in 11.5 seconds. What is the runner's average running rate in meters per second?

Answer 1

Average speed is equal to distance divided by time.

Explanation:

`v_(av) = (Delta d) / (Delta t)`

Plug these values into your formula, then into your calculator - should give you an average speed of 8.7 `m/(s^2)`
