316 cents Question based on:

Kinematics. Here, we have the distance covered in one trip and the respective speeds. So, we can find the total distance travelled and the time. And then calculating the average speed.

GiveN:

Distance between two station is 500 km

Speed in first trip = 50 km/hr

Speed in return trip = 25 km/hr

Step-by-step Explanation:

Average speed is given by Total distance covered / Total time taken in the journey. Here,

Total distance travelled

= 500 × 2 km

= 1000 km

Time taken in trip 1:

= Distance / Speed

= 500 km / 50 km/hr

= 10 hr

Time taken in return trip:

= Distance / Speed

= 500 km / 25 km/hr

= 20 hr

Total time taken = 30 hr

Average speed of the journey:

= Total distance / Total time taken

= 1000 km / 30 hr

= 100/3 km/hr

= 33.34 km/hr (approx.))

Hence,

The average speed of the train during the journey is 33.34 km/hr. And we are done! :D
