Question

Two trains of length 300 m and 250 m running in opposite direction at the speed of 50 km/he and 40 km/he requires how many seconds to cross each other?​

Answer 1

Answer:

Step-by-step explanation:

Trains are moving in opposite directions so their relative velocity will be 85+85=170kmph= 47.22m/s

distance traveled by one train to cross other is 300+250=550m.

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