we have to convert the rate from pints per minute to gallons per hour
1 pint = 0.125 gallon
1 minute - 1/60 hours
we can write 15 pints per minute as
15 pints / 1 minute
to convert pints to gallons we have to multiply by 0.125 gallon/pint
to convert minutes to hours we have to multiply by 1/60 hours/minute
[tex] \frac{15 pints*0.125 gallons/pint}{1 minute * 1/60 hours/minute} [/tex]
= [tex] \frac{15*0.125*60 }{1} = 112.5
[/tex]
rate is 112.5 gallons/hour
