Answer:
The groups walking speed is [tex]1\frac{7}{8}\frac{miles}{hour}[/tex] or [tex]1.875\frac{miles}{hour}[/tex]
Step-by-step explanation:
we know that
To find the speed divide the distance by the time
so
[tex]\frac{(3/8)}{(1/5)}=\frac{15}{8}\frac{miles}{hour}[/tex]
Convert to mixed number
[tex]\frac{15}{8}=\frac{8}{8}+\frac{7}{8}=1\frac{7}{8}\frac{miles}{hour}[/tex]
