Question

$How much time does a train of length 200m and travelling at a speed of 30km/h take to pass a stationary train of length 300m? \ \textless \ br /\ \textgreater \ [tex]\ \textless \ br /\ \textgreater \ \bold{\huge{\red{\boxed{Please Answer}}}}$

Answer 1

speed of train 30kmph
30kmph=30*5/18=25/3 m/s
now 25/3=200+300/t
=>25/3=500/t
=>t=60
time required=60sec =1 min
