Question

Water flows through a pipe at a rate of 9 gallons every 8 minutes. Express this rate of flow in fluid ounces per hour.

Answer 1

Answer:

$Rate = 8640 fl\ oz/hour$

Step-by-step explanation:

Given

Rate: 9 gallon in every 8 minutes

Required

Express in fluid ounces per hour

Express rate as follows;

$Rate = \frac{9\ gallon}{8\ minutes}$

1 gallon = 128 fluid ounces;

So:

$Rate = \frac{9 * 128 fl\ oz}{8\ minutes}$

1 minutes = 1/60 hour;

So:

$Rate = \frac{9 * 128 fl\ oz}{8 * \frac{1}{60} hour}$

$Rate = \frac{1152 fl\ oz}{ \frac{8}{60} hour}$

$Rate = 1152\ fl\ oz/ \frac{8}{60}\ hour$

$Rate = 1152* \frac{60}{8}\ fl\ oz/hour$

$Rate = \frac{1152*60}{8}\ fl\ oz/hour$

$Rate = \frac{69120}{8}\ fl\ oz/hour$

$Rate = 8640 fl\ oz/hour$
