Question:
Two trains start simultaneously from stations A and B, 400 km apart, toward each other. Train from A moves at 60 km/h and from B at 40 km/h. Where will they meet from station A?
400 km दूर stations A और B से दो ट्रेनें एक साथ एक दूसरे की ओर चलीं। A से 60 km/h और B से 40 km/h पर। A से कितनी दूर मिलेंगी?
Options:
- a) 200 km
- b) 220 km
- c) 240 km
- d) 160 km
- a) 200 km
- b) 220 km
- c) 240 km
- d) 160 km
correct answer : c)
Explanation:
Combined speed = 100 km/h. Time = 400/100 = 4 hours. Distance from A = 60*4 = 240 km.
संयुक्त गति = 100 km/h। समय = 4 घंटे। A से दूरी = 60×4 = 240 km।
