What I got so far: So it started at 6 gallons, and in 10 hours was empty. That means the leak is 6 gallons per 10 hours
Convert the leak rate of 10 gallons per 6 hours to ounces per hour.
10 gallons= 1280 oz.

768/10

That doesn't really help

I have to explain how I got the answer, and pretend like I am walking someone through the problem.
OpenStudy (tgannon998):
128 ounces in a gallon
6 gallons so you multiply 6 gallons by the number of ounces in a gallon and you get the total number of ounces. then you divide it by the total number of hours
OpenStudy (mathsucks321):
Is that all?
OpenStudy (tgannon998):
yes
OpenStudy (mathsucks321):
Can you maybe do it with the numbers?

OpenStudy (mathsucks321):
That all?
OpenStudy (tgannon998):
yep
OpenStudy (mathsucks321):
So the answer is 76.8
