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 ?
Choose the most appropriate option
A) 7.76 kms	B) 8.76 kms	C) 5.76 kms	D) 3.76 kms	E) 4.76 kms

Rationale: "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 answer : c"
Answer: C
