Question

Seth's family plans to drive 220 miles to their vacation spot. They would like to complete the drive in 4 hours.

Find the average speed in miles per hour needed to make the trip in the desired.

Answer 1

Answer:55

Explanation:

You can write the equation as 220 miles over 4 hours = x over 1 hour. X represents the average speed in miles per hour. You need to cross multiply 220 and 1 to 4 and x. You get 220=4x. You just simply divide 4 on each side of the equation and get x=55, so the average speed in mph is 55.
