Answer:
Option C.
Step-by-step explanation:
The distance of the car from the stop sign, d , in feet, at time t , in seconds, can be found using the equation
The average rate of change of a function f(x) on [a,b] is
We need to find the average speed of the car, in feet per second, between t=2 and t=5.
At t=2,
At t=5,
The average speed of the car, in feet per second, between t=2 and t=5 is
The average speed of the car, in feet per second, between t=2 and t=5 is 7.7 feet per second.
Therefore, the correct option is C.
