Relative speed ( opposite direction )=S1+S2
Distance = Speed × Time
1km∕h=5∕18m∕s
When two trains cross each other, the total distance covered is the sum of their lengths.
Calculation:
Relative speed =50km∕h+110km∕h=160km∕h
Convert relative speed to m∕s :
⇒160km∕h=160×‌

Let the length of train 2 be L2.
Total distance covered =L1+L2=500+L2 meters
Using Distance = Speed × Time:
