How long will a 150 m long train running at a speed of 60 km / hr take to cross the bridge of 300 m long ?

A37 seconds

B35 seconds

C25 seconds

D27 seconds

Answer:

D. 27 seconds

Read Explanation:

km/hr × 5/18 = m/sec ⇒ 60 × 5/18 = 50/3 m/sec Total distance to cover, ⇒ 150 + 300 ⇒ 450 m Using the formula, ⇒ 50/3 = 450/Time ⇒ Time = (450 × 3)/50 ⇒ Time = 27 sec.
