Answer :-Jerry hears
per hour.
Explanation:-
As time is given in mixed fraction , thus convert it into improper fraction
time![=2\frac{3}{8}=\frac{19}{8}\ hours](/tpl/images/0851/1559/e8dee.png)
The total number of cases Jerry hears in
=5 cases
⇒The number of cases Jerry hears in 1 hour![=\frac{5}{\frac{19}{8}}\ cases\\=\frac{5\times8}{19}\ cases.........[\text{division property in fraction}]\\=\frac{40}{19}\ cases=2\frac{2}{19}\ cases](/tpl/images/0851/1559/b9696.png)
∴Jerry hears
per hour.
