The formula  $S=\sqrt{30fd}$  relates the speed S in miles per hour a car was traveling to the length d in feet that the car skidded when brakes were applied. The variable f is the coefficient of friction, which varies depending on the road surface and the condition of the tires. Which set of numbers contain the value of S for f = 0.8 and d = 51
