Question

A person walks 1/3 mile in 1/9 hour. At what speed is the person walking in miles per hour?

Answer 1

Speed (v) could be determined using this following formula
v = distance ÷ time

plug in the numbers
v = $\frac{1}{3} : \frac{1}{9}$
v = $\frac{1}{3} \times \frac{9}{1}$
v = 9/3
v = 3

The speed is 3 miles per hour
