A train running at a speed of 60 km/h crosses a pole in 9 seconds. What is the length of the train?

1. 120 metres
2. 180 metres
3. 324 metres
4. 150 metres

Correct answer: 150 metres

Solution

When a train crosses a pole, the distance covered is equal to the length of the train. Converting 60 km/h to m/s gives 16.67 m/s, and in 9 seconds the train covers about 150 m.

• Direction (46–48): Read the data given below carefully and answer the question. A train runs between four stations A, B, C and D on Monday and Tuesday. The average speed of the train on Monday during the whole journey is 50 km/h and the average speed on Tuesday during the whole journey is 62.5 km/h. On Monday, the train takes one hour less to cover the distance between A and B than it does on Tuesday. The train takes equal time to cover the distance between B and C on both days, while it takes three hours more to cover the distance between C and D on Monday than on Tuesday. The distance between A and B is 40% less than that between C and D. The distance between B and C is 50% more than that between A and B. Note: There is no halt or stoppage from station A to D. Find the total time taken by the train to cover the distance from A to D on Tuesday.
