5. A train 360360 metre long runs with a speed of 4545 km/hr. What time will it take to pass a platform of 140140 metre long?A. 3

Answer 2

1) The time taken by the man to pass the tunnel = 2 minutes.

2) The time taken by the train to cross the platform = 6 minutes.

3) The distance between Delhi and Patna = 600 km.

• Time = distance / speed

• The time taken by the man to pass the tunnel = (2 / 60) hr

                                                                                  = 2 minutes

• The time taken by the train to cross the platform = (1.5+2.5) km / 40 kmph

                                                                                        = 6 minutes

• The distance between Delhi and Patna = 80kmph * 7.5 h

                                                                     = 600 km
