Hi guys today we are going to explore  30 advance MCQ question based on speed time and distance with answer and explanation. 1. A train travels at 60 km/h for the first 2 hours, at 80 km/h for the next 3 hours, and at 50 km/h for the last 4 hours. What is the average speed of the train for the entire journey? A) 56.4 km/h B) 62.5 km/h C) 68.8 km/h D) 72.6 km/h Answer: B) 62.5 km/h Explanation: The total distance covered by the train is 260 + 380 + 4*50 = 460 km.
