Answer:
The car's average speed is 16 feet per second.
Explanation:
The expression for the average speed is as follows;
Given expression of distance:
Put t= 4 s.
d(4)= 36 ft
Put t= 7 s in the given expression.
d(7)= 84 ft
Calculate the car's average speed over the interval of time from t = 4 seconds to t = 7 seconds.
A.S= 16 feet per second
Therefore, the car's average speed is 16 feet per second.
