Question

The two trains moving in opposite directions on parallel rails at 40km/hrand 35km/hr Cross each other in 1i seconds if the length of one train is 205 m find the length of other​

Answer 1

Answer:

relative speed is 40+35 which is 75km/hr which is 270 m/s

and time is 1s

and total length of trains is 205 m+x

hence

205+x/ 1is 270x is 270-205

65m

therefore length of other train is 65m
