A Running Train Passes A Pole In 15 Seconds And A Platform Of 100 M Long In 25 Seconds. Find The Length Of The Train? |
|
Answer» Let's suppose TRAIN is RUNNING with a speed of X m/sec having a length of x METERS, so Speed = length/time s= x/15 (while passing a POLE) ........... (i) s= (x+100)/25(while passing the platform)...........( ii) Equating both equations, we get x/15= (x+100)/25 5x=300+3x 2x=300 x=150 meters.
