# Accelerating and Braking a car

Curves at high speed can be very dangerous, even if you're in a sports car with different systems such as stability control, traction control and abs brakes.

John accelerated his sportive car to a speed of 216 km/h, but the road is too sinuous and he had to reduce the speed of his car to 72 km/h in 3 seconds, approximately how much distance was traveled by John in this time?
