The horsepower, H(s), required for a racecar to overcome wind resistance is given by the function H(s) = 0.003s2 +0.078 -0.027, where s is the speed of the car in miles per hour. What is the average
rate of change in horsepower per unit speed if the racecar increases in speed from 80 mph to
100 mph?

i can't read the graph

step-by-step explanation:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
