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

Answer:

$2\frac{2}{19}$ cases does he hear per hour.

Step-by-step 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 $2\frac{3}{8} =\frac{19}{8}$  hours

or we can write this as;

For every $\frac{19}{8}$ hours he hears 5 cases.

Unit rate per hour = $\frac{5}{\frac{19}{8}} = \frac{5 \times 8}{19} = \frac{40}{19}=2\frac{2}{19}$ cases.

Therefore, he hears $2\frac{2}{19}$ cases per hour at this constant rate.
