Find the average speed in given time interval.

Answer to Problem 66E
The average speed of car from
Explanation of Solution
Given:
The function and distance s
Let consider a moving car with the following function and distance s
To find the average speed of car from
Average speed of car from
Hence, the average speed of car from
The time and distance are directly proportionate to each other. That is, if the time increases, the distance will also increase.
Due to this as the time increase the average speed will increase.
Also, the average speed of car from
Therefore, the average speed of car from
