Question:

A train 200 m long running, at a speed of 36 km/h, takes 55 seconds to cross a bridge completely. What is the length of the bridge?

Options:

300 m

375 m

350 m

320 m

Correct Answer:

350 m

Explanation:

Speed of train = 36 × $\frac{5}{18}$ = 10 m/sec

Let Length of bridge = B meter

Distance = Speed × Time

200 + B = 10 × 55

200 + B = 550

B = 550 - 200

= 350 m

So Length of bridge = 350m
