Answer:
8 Gallons Per Minute
Step-by-step explanation:
Well in the question it doesn't specify what you need to find but out of my knowledge with questions from school I think it's the way I answered it.
58-18 = 40
40 gallons were filled in 5 minutes
[tex]40^{1}[/tex] divided by [tex]5^{1}[/tex] = [tex]8^{1}[/tex]
8 gallons were filled per minute
