Question

An ice machine uses 3 gallons of water every 9 hours. How many gallons of water does it use each hour? How many hours does it take to use one gallon?

Answer 1

A ) For 1 hours machine uses 0.33 gallons of water

B ) For 1 gallon of water , machine will take 3 hours

Explanation:

Given as :

∵ For every 9 hours , machines uses 3 gallons of water

∴ For 1 hour , machines uses
`(3)/(9)` gallons of water

Or, For 1 hours machine uses
`(1)/(3)` gallons of water

I.e For 1 hours machine uses 0.33 gallons of water

Now, Again

∵ For 3 gallons of water , machine takes 9 hours

∴ For 1 gallon of water , machine will take
`(9)/(3)` hours

I.e For 1 gallon of water , machine will take 3 hours

Hence ,

A ) For 1 hours machine uses 0.33 gallons of water

B ) For 1 gallon of water , machine will take 3 hours
