Answer:
A ) For 1 hours machine uses 0.33 gallons of water
B ) For 1 gallon of water , machine will take 3 hours
Step-by-step explanation:
Given as :
∵ For every 9 hours , machines uses 3 gallons of water
∴ For 1 hour , machines uses [tex]\frac{3}{9}[/tex] gallons of water
Or, For 1 hours machine uses [tex]\frac{1}{3}[/tex] 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 [tex]\frac{9}{3}[/tex] 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
