Correct answer: (A) 914.44
Relative speed = (60+50) km/h = 110 × 5/18 = 30.56 m/s. Total distance = speed × time = 30.56 × 44 = 1344.44 m. Length of other train = 1344.44 − 430 = 914.44 m.

सही उत्तर: (A) 914.44
सापेक्ष चाल = (60+50) km/h = 110 × 5/18 = 30.56 m/s। कुल दूरी = चाल × समय = 30.56 × 44 = 1344.44 m। दूसरी ट्रेन की लंबाई = 1344.44 − 430 = 914.44 m।
