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
