Two trains of equal length are running on parallel lines in the same direction at 56 km/hr and 46 km/hr. The faster train passes the slower train in 36 seconds. The length of each train is:
Thrice the speed of a boat downstream is equal to four times the speed upstream. The ratio of its speed in still water to its speed in current is-
A tank is filled in 8 hours by three pipes A, B and C. The pipe C is twice as fast as B and B is twice as fast as A. How much time will pipe A alone take to fill the tank?
Two trains A and B start running together from the same point in the same direction, at the speed of 60 kmph and 72 kmph respectively. If the length of each of the trains is 210 meters, how long will it take for B to cross train A?
