Question

Use function notation to represent the average speed of the car on the interval from t = 2 to t = 7 .

Answer 1

Answer:

$Average\ Speed = \frac{s(7) - s(2)}{5}$

Step-by-step explanation:

Given

t = 2 to 7

Required

Find the average speed over these intervals

The function is not given; so, I'll represent the function as s(t)

When $t = 2;$

$s(t)= s(2)$

When $t = 7$

$s(t) = s(7)$

$Average\ Speed = \frac{Change\ in\ Distance}{Change\ in\ Time}$

This gives:

$Average\ Speed = \frac{s(7) - s(2)}{7 - 2}$

$Average\ Speed = \frac{s(7) - s(2)}{5}$
