Q. A man rows a boat at the speed of 6 km./hr. in still water. When the river flows with the speed 1.2 km./hr, then it takes 1 hour for the man to row from one place to another. How far is that place?

A) 1.44 km

B) 3.18 km

C) 2.88 km

D) 4.81 km

2.88 km

Additional Information > Exam point of View

The effective speed of the boat downstream is 6 + 1.2 = 7.2 km/hr. Distance = speed × time = 7.2 × 1 = 7.2 km. Thus, the place is 7.2 km away.
