Question

A swimming pool is being filled ata rate of 15 pints per minute. How many gallons per hour is this?

Answer 1

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

$\frac{15 pints*0.125 gallons/pint}{1 minute * 1/60 hours/minute}$

= $\frac{15*0.125*60 }{1} = 112.5$

rate is 112.5 gallons/hour

Answer 2

15(pints) x 60(min)=900 pints
.125 x 900= 112.5
 112.5 gallons per hour.
