In Germany there are no speed limits on some portions of the autobahn. The
distance required to stop a car is given by the following function:
x: Velocity of car (kilometers per hour)
D(x): Stopping distance (meters)
D(x) = .0056x2 +.14x
The function used to convert miles per hour into kilometers per hour is as follows:
X: Miles per hour
k(x): Kilometers per hour
k(x) = 1.6071x
Determine the function to convert miles per hour into stopping distance.
