Homework Statement
Two pumps of different sizes can empty an entire fuel tank in 4.8 hours. Used alone, the larger pump would empty the tank 4 hours less than would the smaller pump. If using only the smallest pump How long will it take to empty the tank?
Homework Equations
X = small pump
X-4hours = bigger pump
Y = 4.8 hours
This is what I understand so far. I am not sure what to do next.
The Attempt at a Solution
4.8 = x - 4
would that mean small pump needs 8.8 hours? am I doing this right?
