A man can row 6 kmph in still water. When the river is running at 1.2 kmph, it takes him 1 hour to row to a place and back. What is the total distance traveled by the man ?

Correct Answer: 5.76 kms

Explanation:

Speed in still water = 6 kmph


Stream speed = 1.2 kmph


Down stream  = 7.2 kmph


Up Stream = 4.8 kmph


x/7.2 + x/4.8 = 1


x = 2.88


Total Distance  = 2.88 x 2 = 5.76 kms
