A train covers 100 km at a speed of 50 km/h. Due to track repair, it reduces its speed by 40% for the next 60 km. What is the total time taken for the full journey?
2 hours
4 hours
5 hours
10 hours
Answer: B
Time for the first 100 km=100/50=2 hours. Reduced speed=50×60%=30 km/h. Time for the next 60 km=60/30=2 hours. Total=4 hours.
एक ट्रेन 50 किमी/घंटा की गति से 100 किमी की दूरी तय करती है। पटरी की मरम्मत के कारण अगले 60 किमी तक उसकी गति 40% कम हो जाती है। पूरी यात्रा में कुल कितना समय लगेगा?
2 घंटे
4 घंटे
5 घंटे
10 घंटे
उत्तर: B
पहले 100 किमी का समय=100/50=2 घंटे। कम गति=50×60%=30 किमी/घंटा। अगले 60 किमी का समय=60/30=2 घंटे। कुल समय=4 घंटे।
