Question

ye raha que..solve pls early

Answer 1

Relative Velocity= 5 kmph
Distance= 0.4 km
Time= 0.4/5 = 0.1 hours= 288 seconds = 4 minutes 48 seconds

Answer 2

As per the question,
Here, both the trains are moving in same direction , So,
Relative speed = (35-30)Kmph = 5Kmph.
And, Distance covered in crossing each other
= (200+200)= 400 m = 400/1000 = 0.4 Km.
So, time taken = 0.4/5 Hour = 0.08 hr = 0.08*60*60 = 288 sec.
