Problems on Trains
Rule 01. When train passes a pole or a stationary man it should travel the length equal to the length of the train. Rule 02. When a train passes a platform it should travel the length equal to the sum of the lengths of train and platform. Rule 03. When two trains are moving in opposite directions their speeds should be added to find the relative speed. Rule 04. When two trains are moving in the same direction the relative speed will be the difference of their speeds. Rule 05. Two trains are moving in the same direction at x km/hr and y km/hr (where x > y). If the faster train crosses the slower trains in ‘t’ seconds, then the length of the faster train is given by - [5/18(x-y)*t] metres. Rule 06. A train running at x km/hr takes t1 seconds to pass a platform. Next it takes t2 seconds to pass a man walking at y km/hr in the opposite direction, then the length of the train is - [5/18(x+y)t2] metres and that of the platform is -...
