Question

The polynomial 3.675v + 0.096v2 is used to estimate the stopping distance in feet for a car whose speed is v miles per hour on flat dry pavement.
What is the stopping distance for a car traveling at 70 miles per hour?

Distance = feet

Answer 1

3.675v + 0.096v^2.....where v is the speed of the car in mph

at 70 mph....so sub in 70 for v

3.675(70) + 0.096(70^2) =
257.25 + 470.4 =
727.65 ft <===
