Problem on speed taken by train
The problem on trains are important chapter for easily get the marks in competitive exam papers.you just remember the way of train cross the object and speed ,time and distance.There are train based problem based on two object,Here we learn the problem on speed taken by train pass a pole ,a man or light lamp or platform bridge. First is Train and second object is that which is crossed by the train.
Problem on speed taken by train
Example 1: A Local train whose length is 150 meter long and a bridge length is 550 meter to cross the bridge by local train is 50 sec,Then find the speed of train to crossing a bridge.
Answer: At first we add the length of both train and bridge that is 150 + 550 = 700 meter,and we know the formula of speed = Distance / Time , So 700 / 50 = 15 meter / sec.
Example 2: A boy is standing on a railway bridge and which is 150 m long. He find that a train passes the bridge in 40 seconds but the train himself in 10 sec,Find the length of the train and speed .
Answer: First we find the length of train, the we assume that length of train be L meters.
than, L / 10 = L + 150 / 40 = 40 L = 10L + 1500 ,
so, L = 50 meter. and now speed of train is D / T = 50 / 10 = 5 m / sec . and now convert it into 5 x 18 / 5 = 18 Km / hr.
So speed of train is 18 Km / hr.
