You can u understand this question by this example solved by me.
Its of same type
Distance of Platform is 122 metres in length & Time of 17 seconds (TR=7.17 + T3.83)
Distance of Bridge is 210 metres in length & Time of 25 seconds (TR= 8.4 +T2.6 )
Distance of Platform & Train = 187 metres divided by 17 seconds (TR of 11)
Distances of Bridge & Train = 275 metres divided by 25 seconds (TR of 11)
Confirms length of Train is 65 metres in length
Speed of Train is 39.6 km/h.
122+210+65+65 = 462 metres divided by 42 seconds = 11 metres per second.
hope u liked it
thank you..
