Time Distance and Speed
The driver of a passenger train travelling at 40kmph notices that a goods train moving in the opposite direction
fully passes by him in 12s. What is the length of the goods train if it is travelling at a speed of 60kmph?
Read Solution (Total 1)
-
- The relative speed of the train=(40+60)Kmph or 100kmph or100*5/18=27.77m/s
Now the equation is
time the goods train passed=(Length of the goods train/relative speed of the train in seconds),12=L/27.77
Thus, the length of the train =12*27.77=333m approx - 13 years agoHelpfull: Yes(3) No(0)
