A man takes 6.5 hours in walking a certain distance and riding back on horse. If he ride both side on horse he would have saved 2 hrs 10 min. How much time does he take on walking both sides?
Answer & explanation
Correct answer: option 4
1st Case : Going by walk + riding on horse
Time taken = 6:30 hrs.
2nd Case : Going & coming back on horse
Time 6:30 - 2:10 = 4:20 hrs.
Therefore, one side on horse takes = 2:10 hrs.
And, one side walk takes = 6:30 - 2:10 = 4:20 hrs.
Walking both sides will take = 2 × (4:20) hrs. = 8:40 hrs.
