The function s(t) represents the position of an object at time t moving along a line. suppose s(2)=150 and s(5)=237. find the average velocity of the object over the interval of time [1, 3].

29 is answer.

Step-by-step explanation:

Given that the function s(t) represents the position of an object at time t moving along a line. Suppose s(2)=150 and s(5)=237.

To find average velocity of the object over the interval of time [1,3]

We know that derivative of s is velocity and antiderivative of velocity is position vector .

Since moving along a line equation of s is

use two point formula

gives the position at time t.

Average velocity in interval (1,3)

=

A is the answer because to actually get the answer you would have to find out how much 2 hot dogs cost which is $2.50 and so it says how much money did he spend altogether - so you would have multiply 16 and $2.50 to get your answer and thats why A is the answer
