Question

A water faucet leaked 3 2/6 liters of water every 3/5 of an hour. It leaked at a rate of how many liters per hour?

Answer 1

Our water faucet leaked 3 2/6 liters of water every 3/5 of a hour. 
We are to find the rate in liter per hour at which the water faucet leaked. 

First, use the number of liters the water faucet leaked in 3/5 of a hour. 

This is 3 2/6 = 20/6

Therefore, the number of liters of water faucet leaked in 1 hour is

(20/6) / (3/5) 

Before we solve this, we should simplify,

20/6 can be simplified to 10/3

3/5 cannot be simplified

Then, we should modify our problem to use reciprocation instead of a complex fraction,

(10 • 5) / (3 • 3) 

This equals 50/9

Now, solve 50/9 for 5.555555555556

This rounds to 5.6

Thus, the required rate at which the water faucet leaked is 5.6 liters per hour.
