Two trains start their journeys with velocities of 60 km/hr and 30 km/hr respectively in opposite directions from two different stations 120 km apart. The train of higher velocity is stopped after 40 min of its departure. When will the other meet the first one?

Correct answer: At 160 minutes

Explanation: ✅ Correct Answer: A. At 160 minutes 📚 Explanation: In 40 minutes, the fast train covers 40 km and the slow train covers 20 km. The gap is now 60 km. Since the fast train stops, the slow train must cover the remaining 60 km alone. At 30 km/hr, the slow train takes 120 minutes more. Adding the initial 40 minutes, the total time to meet is exactly 160 minutes.
