Rebecca's ERROR
Rebecca wrongly used the formula to calculate the average rate of change from x = -1 to x = 3.
She should have used the correct formula to calculate the average rate of change from x = -1 to x = 3 which is:
Average rate = [f(3) - f(-1)] / [3 - (-1)]
But, she reversed the formula.
The correct solution
Considering the graph
Rebecca wants to find the average rate of change from x = -1 to x = 3.
so
at x₁ = -1
at x₂ = 3
Using the formula, we can determine the average rate of change from x = -1 to x = 3
Average rate = [f(3) - f(-1)] / [ x₂ - x₁]
Therefore, the average rate of change from x = -1 to x = 3 will be:
Average rate = 15/8
the given info is as
1/4th hour
So, if we multiply this by '4', we will get 1 hour rate.
So, multiply the mile by 4, we get:
So,
7/8 mile in 1/4th hour
7/8 * 4 miles in 1/4 *4 hours
Which is 7/2 miles in 1 hours
Or,
3.5 miles in 1 hour
