The function​ s(t) represents the position of an object at time equals 86s(3)=86

Question

The function s(t) represents the position of an object at time t moving along a line. Suppose s left parenthesis 3 right parenthesis equals 86s(3)=86 and s left parenthesis 5 right parenthesis equals 118s(5)=118. Find the average velocity of the object over the interval of time left bracket 3 comma 5 right bracket .[3,5].

Answer 1

Velocity is the change in position over time.

 

s(3) = 86

s(5) = 118

 

Then velocity = s(5)-s(3)

                       ----------

                          5-3

 

(118-86)/(5-3) = 32/2 = 16
