Atruck can travel 80 miles in the same time that ot takes a car to travel 90 miles. if the truck’s rate is 5 miles per hour slower than the car’s, find the average for each.

The truck was going 40 miles per hour

The amount of time was 2 hours:
(90-80: 10)(10/2=5)

80 divided by two is 40

The car was going 45 miles per hour

(90-80:10)(10/2=5)

90 divided by two is 45

Hopefully you find this helpful

The first option would be correct if it were one half and not one
