(F) f(x) = |x+ 4|
(G) f(x) = |x– 4|

(K) f(x) = |x– 4| – 4
Two hoses attached to separate water sources are available to fill a
cylindrical swimming pool. If both hoses are used, the time it will take
to fill the pool can be represented by the following equation: 
, where T1 and T2 represent the time needed for hoses 1 and 2, respectively, to fill the pool on their own, and Tc
represents the time needed for hoses 1 and 2 to fill the pool working
together. If hose 1 alone can fill the pool in exactly 20 minutes and
hose 2 alone can fill the pool in exactly 60 minutes, how many minutes
will it take to fill the pool if both hoses work simultaneously?
(A) 3 (B) 10 (C) 15 (D) 18 (E) 40
