On average, Stan drinks 3/4 of a 8 ounce glass of water in 1/2 of an hour.

sweet [91]

<h3>Stan drinks 12 ounces of water in 1 hour</h3>

Solution:

Given that,

Stan drinks 3/4 of a 8 ounce glass of water in 1/2 of an hour

Which means,

$\frac{3}{4}\ of\ 8\ ounce = \frac{1}{2}\ hour$

$\frac{3}{4} \times 8 = 0.5\ hour\\$

Therefore,

6 ounces is drank in 0.5 hour

We have to find the water he drinks in an hour

Let "x" be the water he drinks in 1 hour

Thus we get,

6 ounce = 0.5 hour

x ounces = 1 hour

This forms a proportion and we can solve the sum by cross multiplying

$6 \times 1 = 0.5 \times x\\\\0.5x = 6\\\\x = \frac{6}{0.5}\\\\x = 12$

Thus, he drinks 12 ounces of water in 1 hour
