Predict the change in a runner’s finishing time with a wind speed of
5meters/second.

The change t was -1.243 seconds

Step-by-step explanation:

We already have the equation that models the change in the runner's time based on the wind speed s.

This relation between t and s is given by a quadratic function.

If the function is:

To predict the change in the completion time when the speed is 5m/s, we must replace s = 5 in the equation.

Then we substitute s = 5

The change was -1.243 seconds
