Answer: 349.6 gallons
Step-by-step explanation:
This is a simple proportion problems.
The flow rate = 87 . 4 gallons was dispensed in 15 minutes
That is 15 minutes = 87.4 gallons
Therefore 1 minute = ( 87.4/15 ) gallons
Recall 60 minutes = 1 hour
Now in 60 minute = (87.4/15 ×60/1 ) gallons
= 87.4 × 4
= 349.6 gallons
(Invariably) , Alternative method
15 minutes. = 1/4 of an hour 1/4 = 87 .4 gallons. A gallon. = 87.4/1/4
Recall that reciprocal of 1/4 = 4
Now = 87 .4/1/4
=87.4 × 4
Therefore 1 hour = 87.4 × 4 × 1
= 349 . 6 gallons
