The janitor at a school discovered a slow leak in the pipe. the janitor found that it was leaking at a rate of 4 fl oz per minute. how fast was the pipe leaking in gallons per hour plz you

Well... first, how many oz are in one gal? i think its... 128. Don't quote me. But I'm pretty sure its 128. So then... how many minutes are in an hour? 60. So... 

And the answer is: 1.87 Gallons. 

Hope this helps.
