A tap fills a tank in 5 hours, and another tap empties it in 7 hours. How long will it take to fill the tank if both taps are open?
Filling tap fills 1/5 of tank per hour Emptying tap empties 1/7 of tank per hour Net filling = 1/5 - 1/7 = (7-5)/35 = 2/35 per hour Time to fill = 1 / (2/35) = 35/2 = 17.5 hours
Reasoning
Two trains move in the same direction at 50 kmph and 32 kmph respectively. A man in the slower train observes that 15 seconds elapse before the faster train completely passes by him. What is the length of the faster train?
Relative speed = 50 - 32 = 18 kmph = 18 × 5/18 = 5 m/s Time = 15 seconds Length of faster train = Relative speed × Time = 5 × 15 = 75 meters
