Chapter 0, Problem 3PR

To determine

To find: the number of hours taken for the bathtub to get filled.

Answer to Problem 3PR

It takes 25 minutes to fill 500 gallon bathtub completely.

Explanation of Solution

Given:

Time taken to complete 80 gallons of water in the bathtub = 4 minutes

Calculation:

So, that means.

The amount of water filled in the bathtub in 1 minute is,

  $=\frac{\text{80gallons}}{\text{4 min}}=\text{20gallons/min}$

Time required to fill 500 gallons of water is

  $=\frac{\text{amount of water in gallons}}{\text{amount of water that can be filled in 1 minute}}=\frac{\text{500 gallons}}{\text{20gallons/minute}}=\text{25minutes}$

Conclusion:

Therefore, it takes 25 minutes to fill 500 gallon bathtub completely.
