We are asked to convert 815 gallons per hour to quarts per second. The solution can be seen below;
There are 4 quarts in a gallon, and there are 60 minutes in an hour. This implies the following;
1) In one hour we would have;
[tex]60\times60=3600\text{ seconds }[/tex]2) In 815 gallons we would have;
[tex]815\times4=\text{ }3260\text{ quarts }[/tex]We can then find the number of quartz per second as
[tex]\frac{3260}{3600}=0.9056[/tex]Answer: The number of quartz per second would be 0.9056
