Best answer
Correct Answer - Option 1 : 1h 25 minutes, 53.9 km/h
Concept:  
  • Distance between two places would be the difference of distances from a common point
  • Speed is calculated by dividing the total distance by the total time
  • Speed = Distance/Time
  • Average Speed = (Total distance covered / Total time taken)


Explanation:

  • The speed of a train does not remain the same throughout the journey.
  • Since average speed considers total distance and total time, hence it remains the same throughout a journey.
  • The total distance between Trichur and Ernakulam is 2356-2280= 76km
  • Time is taken to travel from one station to another is calculated as the difference between departure from the previous station and arrival at the next station.
  • Departure from Trichur 21:10
  • Arrival at Ernakulam: 22:35
  • Time taken to reach from Trichur to Ernakulam is 1 h 25 minutes.
  • Average speed = 76km/1.41h  = 53.9km/h = 894.12m/s


∴ Time taken to reach from Trichur to Ernakulam is 1 h 25 minutes and average speed is 53.9km/h.
