A train covers a distance of 540 km between two stations in 240 minutes. It travels at a speed of 90 km/h to another station in 5 hours. What is the average speed of the train (in km/h)?

Show answer & explanation

Correct answer: B

Explanation

The correct answer is Option 2 i.e. 110.

Distance between two stations = 540 km

Time taken by train to travel between two stations = 240 min

Speed of the train while travelling to another station = 90 km/h

Time taken by the train to travel to another station = 5 hours.

Average speed = Total distanceTotal timeTotal\ distance \over Total\ time

Distance = Speed × Time = 90 × 5 = 450 km

Total distance = 540 + 450 = 990 km

Total Time = 24060240\over 60 + 5 = 4 + 5 = 9 hrs

Average speed = 9909990\over 9 = 110 km/hr

The average speed of the train is 110 km/hr.
