Question

A 600 m long train running 60 km/hour.it passes 2.4 km tunnel how much time taking?

Answer 1

Answer:

Step-by-step explanation:

600 meters = 0.6km

The train will have to travel an extra 0.6km to the 2.4km tunnel because of its length. 0.6 + 2.4 = 3km

60km/h travels 3km in 1/20 of an hour.  (60 / 3 = 20)

1/20 of an hour is 3 minutes, so the answer is (D).
