Answer 2

Question:

A train 150m long running at a speed of 60 km/h crosses a bridge in 30 sec. The length of the bridge is:

Answer :

Given:

Length of train = 150m

Speed of train = 60km/h

Time to cross the bridge = 30 sec

Concept Used:

1 km/hr = 5/18 m/sec

Distance = Speed × Time

Calculation:

Speed of train = 60kmph = 60 × 5/18 = 50/3 m/sec

Let the length of bridge be a m.

Then,

⇒ 50/3 = (a + 150)/30

⇒ 500 = a + 150

⇒ a = 350
