Peter's One tap, working alone at its maximum constant rate, can fill a certain sink in 220 seconds. A second tap, working alone at its maximum constant rate, can fill the same sink in 224 seconds. If both taps work together at their respective maximum constant rates, the time it will take to fill the sink is closest to Answers.
A) 111 seconds B) 130 seconds C) 177 seconds D) 200 seconds E) 270 seconds
Tap 1 : 220 secs   Tap 2 : 224 secs   Considering the average of these 2 taps : 222 secs.   So 1 tap can fill the tank in 222 secs, so 2 taps can fill the tank in 222/2=
