Question

A person walks 2 3 of a mile in 2 9 of a hour. Which complex fraction when simplified will compute the unit rate of miles per hour?

Answer 1

Answer:

$3 mi/hr$

Step-by-step explanation:

The rate of miles per hour refers to the speed, which is calculated with:

$s=\frac{d}{t}$

Where:

$d=\frac{2}{3}mi$

$t=\frac{2}{9}hour$

Replacing all values, we have:

$s=\frac{\frac{2}{3}mi}{\frac{2}{9}hour}=\frac{18}{6} mi/hour\\s=3 mi/hr$

Therefore, the ratio is

$3 mi/hr$

Answer 2

2/3  /  2/9
= 2/3 * 9/2
=18/6
=3

rate = 3 miles per hour
