Question

A mail truck traveled 82 miles in 412 hours. The distance is the product of the rate and the time. To the nearest tenth, what was the average speed of the mail truck?

Answer 1

The average speed of the mail truck is calculated by dividing the distance it traveled, 82 miles, by the time taken, which is 4.12 hours, leading to an average speed of 19.9 miles per hour.

Step-by-step explanation:

To calculate the average speed of the mail truck, we use the formula that states the distance is the product of the rate (speed) and the time. The question states that a mail truck traveled 82 miles in 412 hours. This seems to be a typo, as 412 hours is an impractical amount of time for a mail truck to be driving to cover only 82 miles. Assuming it is a mistake and it should be 4.12 hours which is a more reasonable time frame, we can proceed with the calculation:

Average Speed = Distance / Time

Distance = 82 miles
Time = 4.12 hours

Now, divide the distance by the time to find the average speed.

Average Speed = 82 miles / 4.12 hours
Average Speed = 19.9 miles per hour

To the nearest tenth, the average speed of the mail truck was 19.9 miles per hour.

Answer 2

Divide the number of mile per the number of hours. Your answer should be in mph. V=d/t
d=distance and t=time
