Question

The table shows how far a distance runner has traveled since the race began. What is her average rate of change, in miles per hour, during the interval 0.75 to 1.00 hours?

Answer 1

Please post the table when you get a chance.

That being said, we can still set up the calculations.

Let's let f(0.75) be the speed at 0.75 hours, and f(1.00) be the speed at 1.00 hours.

The rate of change between these two values, therefore, is:

\[\frac{ f(1.00)-f(0.75) }{ 1.00-0.75 }\]
fill in the appropriate values from the table
