Question

Jerry is a judge. He hears 5 cases in 2 3/8 hours. How many cases does he hear per hour

Answer 1

Jerry does
`2.11` cases per hour (Rounded to 2 decimal places). As we cannot do 0.11 cases. We can say Jerry does 2 cases per hour.

Explanation:

to find the number of cases per hour, we have to divide the number of cases by number of hours taken for those cases,

Number of cases per hour =
`(5cases)/(2(3)/(8) hours)`

=
`(5)/((19)/(8) ) \\` cases per hour

=
`(5*8)/(19)` cases per hour

=
`(40)/(19)` cases per hour

=
`2.11` cases per hour (Rounded to 2 decimal places)

As we cannot do 0.11 cases. We can say Jerry does 2 cases per hour.
