A) If you are traveling 37 miles per hour and the car in front of you is traveling 19 miles per hour, how much distance will you cover before you can match their speed?

B)Now assume the vehicle in front of you is stopped, and is 150 feet ahead. If you are traveling 37 miles per hour, will you hit them? Answer 0 for no and 1 for yes.
