Best 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
