Two trains, 148 m and 152 m long,
Two trains, 148 m and 152 m long, are running towards each other on parallel lines at 62 km/h and 46km/h, respectively. In what time will they be clear of each other from the moment they meet?
148 m और 152 m लंबी दो ट्रेने समानांतर पटरियों पर क्रमश: 62 km/h और 46km/h, की चाल से एक दूसरे की ओर बढ़ रही हैं। जिस क्षण वे आपस में मिलेंगी, उससे कितने समय बाद वे एक दूसरे को पार कर लेंगी?
Detailed Solution & Logic
Correct Answer:
10 sec / 10 सेकंड
Lengths of trains = 148 m and 152 m
Total distance to be covered = 148 + 152 = 300 m
Speeds = 62 km/h and 46 km/h
Relative speed (opposite directions) = 62 + 46 = 108 km/h
Convert to m/s:
$108 \times \dfrac{1000}{3600} = 30 m/s $
Time to cross each other = $ \dfrac{300}{30} = 10 s $
Answer: 10 seconds
