Example Input: Question: Tina is speeding on the highway, and a cop is sat on the road with a radar gun to see who to pull over. The cop's gun begins to detect a low frequency, with waves reflected being bunched up. The car was going
Answer: slower
Example Output:

Therefore, the waves the receiver detects have a higher frequency than they would if they were being reflected from a stationary object. The faster the car is moving, the greater the increase in the frequency of the waves.
