Question

The amount of water used to take a shower is directly proportional to the amount of time that the shower is in use. A shower lasting 18 minutes requires 10.8 gallons of water. Find the amount of water used in a shower lasting 4 minutes.

Answer 1

The answer to your question is 2.4 gallons of water.

Step-by-step explanation:

Data

Volume = time

10.8 gallons = 18 min

x = 4 min

Process

1.- Write a proportion to solve this problem

10.8 gallons ------------------- 18 min

x gallons ------------------ 4 min

2.- Simplification

x = (4 x 10.8) / 18

x = 43.2 / 18

3.- Result

x = 2.4 gallons
