Question

Jerry is a judge he hears five cases every two and three eights hours Jerry hears cases at a constant rate how many cases does he hear per hour

Answer 1

`2(2)/(19)` cases does he hear per hour.

Explanation:

Unit rate is expressed as a quantity of 1, such as 3 feet per second or 6 miles per hour, they are called unit rates.

Given: Jerry hears five cases every two and three eights hours.

⇒ 5 cases for every
`2(3)/(8) =(19)/(8)` hours

or we can write this as;

For every
`(19)/(8)` hours he hears 5 cases.

Unit rate per hour =
`(5)/((19)/(8)) = (5 * 8)/(19) = (40)/(19)=2(2)/(19)` cases.

Therefore, he hears
`2(2)/(19)` cases per hour at this constant rate.
