Question

A train travelling at a uniform speed passes a 445 m long platform in 17 seconds and another platform ,175 m long,in 10 seconds.Find length and speed of train?

Answer 1

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.
