Detailed explanation-1: -The Required Answer Is 50 meter (or metre) per second.
Detailed explanation-2: -To answer this question, we need to know the average speed of a train that travels 60 kilometers in 20 minutes. The average speed of a train traveling 60 kilometers in 20 minutes is 3km/min.
Detailed explanation-3: -Total time taken = Time taken to travel from A to B + Time taken to travel from B to A. Because the train starts and ends at the same station, the displacement is zero. Thus the average velocity is zero.
Detailed explanation-4: -option (B) 15 km, is the right answer.
