Question

Two railway tracks one upon the other are running perpendicular to each other. Two Trains A and B are running on these tracks at the speed of 72kmph and 64kmph respectively. if both Trains Cross each other in 10 second. What is the length of Train A​

Answer 1

The length of train A will be 200 meters.

Step-by-step explanation:

The two railway tracks ate perpendicular to each other and two trains A and B are moving on these tracks at the speed of 72 kmph and 64 kmph respectively.

If both the trains cross each other in 10 seconds, then the train A basically moves a distance of its own length with 72 kmph speed in 10 seconds.

Therefore, the length of train A will be $\frac{72 \times 1000}{3600}\times 10 = 200$ meters. (Answer)
