Best answer
Correct Answer - Option 2 : 590 m

Given:

Length of the train = 240 meter

Speed of the train = 60 km/h

Time = 50 sec

Concept:

Length of bridge = (Time × speed) ─ Length of train

Calculation:

Let, length of the bridge = x m

Speed in m/s = 60 × (5/18) = 16.6 m/s

According to the question,

⇒(240 + x)/16.6 = 50

⇒ 240 + x = 50 × 16.6 

⇒ 240 + x = 830

⇒ x = 830 ─ 240

⇒ x = 590

∴ length of the bridge = x = 590 meter
