Answer:
[tex]\frac{40}{19}\frac{cases}{hour}[/tex] or [tex]2\frac{2}{19}\frac{cases}{hour}[/tex]
Step-by-step explanation:
we know that
Jerry hears [tex]5[/tex] cases every [tex]2\frac{3}{8}[/tex] hours
so
To find how many cases does he hear per hour, divide [tex]5[/tex] cases by [tex]2\frac{3}{8}[/tex] hours
convert mixed number to an improper fraction first
[tex]2\frac{3}{8}=\frac{2*8+3}{8}=\frac{19}{8}[/tex]
[tex]\frac{5}{(19/8)} =\frac{40}{19}\frac{cases}{hour}[/tex]
convert to mixed number
[tex]\frac{40}{19}\frac{cases}{hour}=\frac{38}{19}+\frac{2}{19}=2\frac{2}{19}\frac{cases}{hour}[/tex]
