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.)
![(30/6)/(6/6)=(5)/(1)](https://img.qammunity.org/2022/formulas/mathematics/high-school/djcue31zcsl7ky8jhx83fnnw9amra1cacp.png)
