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]
