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}

Week 3: 0.4 * 4,200 = 1,680. 1,680 + 4,200 = 5,880
