    Step-by-step explanation:

    I think you missed the information for the speed recorded by the police.

    Here is my suggestion for the number and way to solve this problem

    A police officer records the speeds of vehicles on a road. What percent of the vehicles were traveling between 51 and 55 miles per hour. Speed (miles per hour) & number of vehicles:

    - 45-50 : 5

    - 51 - 55 : 6

    - 55 - 60 : 3

    - 60 - 65 : 4

    Number of vehicles travelling at a speed of 51 and 55 miles per hour = 6

    and total number of vehicles = 5 + 6 + 3 + 4 = 18

    Therefore, the percentage of the vehicles travelling at a speed of 51 and 55 miles per hour is given by:

    6/18*100% = 33.33%
