yes.
OpenStudy (anonymous):
2 inch^3/sec * t sec = 23040 inch^3
OpenStudy (anonymous):
t=?
OpenStudy (anonymous):
2
OpenStudy (anonymous):
23040/2=11520/60=192/60=3.2?

why am I having to divide by 60 twice in order to get the answer?
OpenStudy (anonymous):
we found how many seconds it takes to fill the tank. The question asks how many hours.
