Correct answer is: 8 hours 35 minutes
Explanation:
Time taken in walking one way + riding other way = 6 hours 35 minutes ... (i)
Time taken in riding both ways = 4 hours 35 minutes ...(ii)
By equation (i) × 2 - (ii),
2 × Time taken in walking one way
= 13 hours 10 minutes - 4 hours 35 minutes
= 8 hours 35 minutes
