Question

Jerry hears 5 case ever 2 3/8 hours Jerry hears a constant rate how many case does Jerry hear per hour

Answer 1

Answer: -Jerry hears
`2(2)/(19)` per hour.

Explanation:

Since time is given in mixed fraction
`2(3)/(8)` , thus first convert it into improper fraction

Time=
`(19)/(8)` hours

The total number of cases Jerry hears in =5 cases

⇒The number of cases Jerry hears in 1 hour

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

Thus, Jerry hears
`2(2)/(19)` cases per hour .

Answer 2

The rate of cases is
`(40)/(19)` per hour

Explanation:

we are given

Total number of cases =5

total time is

`=2(3)/(8)` hour

we can simplify it

total time is

`=(2* 8+3)/(8)` hour

`=(19)/(8)` hour

we can use formula

rate of cases = ( total number of cases)/( total time)

now, we can plug values

Rate of cases is

`=(5)/((19)/(8) )`

`=(40)/(19)`
