Answer

Mark was at the top of an inclined road and he parked his car and went to buy some coffee. Unfortunately, Mark forgot to apply the hand brakes so his car rolled down the inclined road under its weight component. That's why its speed increases while it is moving down the road. At the end of the inclined road, the car starts to roll without friction in a straight line at a constant speed of 10 mi/h (which was its speed at the end of the inclined).
