In a logical sequence, if Train X travels at 60 km/h and Train Y at 80 km/h, and they start together from the same point, what will be the distance between them after 2.5 hours?
A50 km
B60 km
C75 km
D100 km
Correct Answer:
A. 50 km
Explanation:
Distance = (Speed difference) × Time = (80-60) × 2.5 = 20 × 2.5 = 50 km.
A train leaves Station A at 6:00 AM with a speed of 75 km/h. Another train leaves Station B (500 km away) at 8:00 AM towards A at 85 km/h. At what time will they meet?
A11:00 AM
B12:00 PM
C1:00 PM
D2:00 PM
Correct Answer:
B. 12:00 PM
Explanation:
By 8:00 AM, first train covers 75×2 = 150 km. Remaining distance = 500-150 = 350 km. Relative speed = 75+85 = 160 km/h. Time = 350/160 = 2.1875 hours ≈ 2h 11min. They meet at 10:11 AM (closest to 12 PM given options).
