Question

Knighton, Katelyn Susie went on a walk. She walked one-fifth of a mile in one-fourth of an hour. What was her walking speed in miles per hour? mile per hour

Answer 1

Data:

Distance: d

Time: t

d=1/5mile

t=1/4h

The speed is:

$s=\frac{d}{t}$$s=\frac{\frac{1}{5}\text{mile}}{\frac{1}{4}h}=\frac{4}{5}\frac{mile}{h}$

Then, her walking speed is 4/5mile/hour or 0.8mile/hour
