Do not round answer if it results in a decimal.

Vilmos' reaction time is 0.3 seconds. He tried to avoid hitting a student walking on the road. If his car traveled 33 feet before stopping, how fast was he going? How many feet would he travel at that speed?

You're not going to get an accurate answer unless you include all of the variables like weight of the vehicle, condition of the road surface and whether the vehicle has brakes on all four wheels etc.
