Expert Answer

Step 1

Given the distance of an object from an point at time t is given by equation s(t) = t2, where t in seconds and distance in feet.

Average velocity can be calculated by dividing the distance travelled by the total time taken to travel that distance.

Step 2

we need to find the average velocity between t = 2 and t = 5. Here we get the distance travelled by the object in 2 seconds by substitution the value of t in the distacne finction s(t). Similarly we can calculate the distance travelled in 5 seconds by substituting the value of t is distance function s(t).

In 2 seconds obhect travels 4 feet and in 5 seconds object ...
