Question

A full container that holds 96 fluid ounces developed a leak in the bottom. After 72 hours, all the liquid had emptied from the container. What was the average rate at which the liquid drained from the container, in fluid ounces per hour?

Answer 1

96/72, which simplifies to 4/3 or 1.333... fluid ounces per hour 

Answer 2

1.3 fl oz/h

Explanation:

Let

• x = volume of liquid in the container = 96 fl oz

• y = time elapsed = 72 h

The average rate at which the liquid drained from the container is equal to the quotient between y and x. Then, the appropriate algebraic operation is the division.

y/x = 96 fl oz/72h = 1.3 fl oz/h
