Question 1041506: R.A Moyer of lowa State College found, in comprehensive tests carried out on 41 wet pavements, that the braking distance d (in feet) for a particular automobile traveling at v miles per hour was given approximated by d = o.0212*v^7/3
1. approximate the braking distance to the nearest foot for the car traveling on wet pavement at 70 miles per hour.
2. approximately how many feet would it take the car to stop on wet pavement if it were traveling at 50 miles per hour? ( Compute answer to the nearest foot.)

d = 0.0212*v^7/3
at 70 mph, or v=70
d=0.0212*4900*70^(1/3). Or just do it on a calculator and raise 70 to the (7/3) power.
d-428 feet.
-----------------------
d=0.0212*50^(7/3)
d=195 feet.
