Question

A police officer records the speeds of vehicles on a road. What percent of the vehicles were traveling between 46 and 50 miles per hour? Speed (miles per hour) & Number of Vehicles 36 - 40 2 41 - 45 14 46 - 50 18 51 - 55 12 56 - 60 4

Answer 1

Answer: The answer is 36%.

Step-by-step explanation: Given that a police officer records the speeds of vehicles on a road as follows

speed(miles per hour) 36-40 41-45 46-50 51-55 56-60

No. of vehicles 2 14 18 12 4

Number of vehicles travelling at a speed of 46 to 50 miles per hour = 18

and total number of vehicles = 2 + 14 + 18 + 12 + 4 = 50.

Therefore, the percentage of the vehicles travelling at a speed of 46 to 50 miles per hour is given by

`(18)/(50)* 100\%=36\%.`

Thus, the answer is 36%.
