Answer:
L = 200 Meters.
Speed = 200/5 = 40 m/sec.
Step-by-step explanation:
When a train passes a person, it travels its own length.
So this train traveled its own length in 5 seconds.
Let train length = Lmeters.
Speed of train = L/5 m/sec.
When a train passes a platform, it travels platform length and its own.
That means, train traveled L+200 meters in 10 seconds.
Speed of train from above calculation = L+200/10
Since both are equal.
(L / 5) = (L+200)/10
2L = L + 200
L = 200 Meters.
Speed = 200/5 = 40 m/sec.
