A boatman can row with a speed of 10 kmh^-1. If a river of width 2 km flows at 5 kmh^-1, then what is the direction in which the boatman should row to reach a point on the other bank directly opposite to the point from where he started?

The work done by force is defined by W = F.S. In a certain situation F and S are not equal to zero, but work done is zero. From this what can be concluded?
