Answer provided by our tutors
In one day garden hose can fill 1/5 of pool.
In one day larger hose can fill 1/4 of pool.
Let 'x' represent the number of day that are needed for the pool to be filled when both hoses are used.
In one day both hoses will fill 1/x of pool.
1/5 + 1/4 = 1/x

x = 2 days 2*24/9 hr
x = 2 days 5 hr
