Question

Two train of length 300 and 215 are moving each chain has is speed of 45 kilometre per hour and missing in the opposite direction how long will it take them to pass each other​

Answer 1

Answer:

trains are moving in opposite direction so their relative velocity will be85+85=170kmph=47.22m/s

distance travelled by one train to cross another is 300+250=550m

so it will take 550/47.22=11.64 seconds for them to pass each other
