A refueling tanker transfers $450$ gallons of aviation fuel into an aircraft in $15$ minutes. What is the tanker's transfer rate in gallons per hour?

The correct answer is

1,800

The correct transfer rate is found by determining how much fuel is pumped in one minute, which is

450 \div 15 = 30

gallons per minute. Since there are

60

minutes in an hour, multiply this rate by

60

to get

1,800

gallons per hour.

Find the unit rate in gallons per minute.

450 \div 15 = 30

gallons per minute.

This establishes the base rate of fuel transfer before scaling up to an hourly rate.

Convert the per-minute rate to a per-hour rate.

30 \times 60 = 1,800

gallons per hour.

There are 60 minutes in an hour, so the minute rate must be multiplied by 60 to find the hourly rate.
