Answer:
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%
