Suppose that the distance d in feet that a car travels in t seconds is given by d(t) = 2t^2. Calculate the average speed (average rate of change) in feet per second from t = 4 to t = 7. (Enter an exact number.) ____________ feet per second.
Added by Kimberly T.
Step 1
Step 1:** Calculate the distance traveled at t = 7 seconds: \[d(7) = 2(7)^2 = 2(49) = 98 \text{ feet}\] ** Show more…

The distance in feet, f(t), of a car north of an intersection t second since the car started to move can be determined by the function f(t) t2 2t. Use function notation to represent the average speed of the car On the interval from t = 2 to t = 7. b. Determine the average speed of the car On the interval from 2 seconds since the car started to move to 7 seconds since the car started t0 move feet per second
