Answer: 5 gallons per hour.
Step-by-step explanation: To find the unit rate, divide "gallons" by "hours." As we said, we need to find the unit rate. We want a unit rate where 1 is in denominator, so we divide the top and bottom by 6. (Remember, unit means 1.)
[tex]\frac{30/6}{6/6}=\frac{5}{1}[/tex]
Therefore, our answer is 5.
