Question

A police officer records the speeds of vehicles on a road. What percent of the vehicles were traveling between 41 and 45 miles per hour?

Answer 1

Answer:

28%

Step-by-step explanation:

Here is the missing table from the question:

Speed (mph) Number of Vehicles

36-40                2

41-45               14

46-50               18

51-55               12

56-60                4

Given: A police officer records the speeds of vehicles on a road.

Now, finding the percent of vehicles traveling between 41 and 45 miles per hour.

First, calculating the total number of vehicles.

Total vehicles= $2+14+18+12+4= 50$

Vehicles travelling at speed of 41-45 mph= 14

Formula;  percent of vehicles traveling between 41 and 45 mph= $\frac{vehicles\ travelling\ 41-45\ mph}{Total\ number\ of\ vehicles} \times 100$

⇒ Percent of vehicles traveling between 41-45 mph= $\frac{14}{50} \times 100= 14\times 2$

∴ Percent of vehicles traveling between 41-45 mph is 28%
