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
