A group walked 3/8 mile in 1/5 hour. Which is the groups walking speed in miles per hour

gogolik [260]

Answer:

The groups walking speed is $1\frac{7}{8}\frac{miles}{hour}$ or $1.875\frac{miles}{hour}$

Step-by-step explanation:

we know that

To find the speed divide the distance by the time

$\frac{(3/8)}{(1/5)}=\frac{15}{8}\frac{miles}{hour}$

Convert to mixed number

$\frac{15}{8}=\frac{8}{8}+\frac{7}{8}=1\frac{7}{8}\frac{miles}{hour}$
