Answer: 2 hours 27 minutes
Explanation:
If 1 hose filled 2.38 gallons in 1 minute.
Then, 350 gallon will be filled in Z minutes
Now cross multiply
2.38 gallons = 1 minute
350 gallons = Z minute
2.38 x Z = 350 x 1
2.38Z = 350
Divide both sides by 2.38 to obtain value of Z
2.38Z / 2.38 = 350 / 2.38
Z = 147 minites
Since, answer must be provided in hours, convert 147 minutes to hours
60 minutes = 1 Hour
Then 147 minites = 120 + 27 minutes
So, 147 minutes = 2 hours and 27 minutes
Thus, it will take 2 hours 27 minutes for the hose to fill the 350 gallon.
