Answer» Correct Answer - Option 1 : 12 hr 14 min Given: Average Speed of train is 50 kmph Distance to travel is 600 km Resting time after every 75 km is 2 min Concept Used: Total time = travelling time + resting time Time = distance/speed Calculation: ⇒ Travelling time = 600/50 = 12 hr Total stops = (600/75) – 1 = 8 – 1 = 7 ⇒ Resting time = 7 × 2 = 14 min ∴ Total time taken to reach destination is 12 hr 14 min |
