A boat man can row with a speed of 10 ...

A boat man can row with a speed of ` 10 km h^(-1)` in still water. If the river flows steadily at ` 5 km //h`, in which direction should the boatman row in order to reach a point on the other bank directly opposite to the point from where he stared ? The width of the river is ` 2 km`.

To solve the problem step by step, we can follow these instructions: ### Step 1: Understand the Problem We have a boatman who can row at a speed of \(10 \, \text{km/h}\) in still water, and the river flows at a speed of \(5 \, \text{km/h}\). The goal is to determine the angle at which the boatman should row to reach a point directly opposite his starting point on the other bank of the river, which is \(2 \, \text{km}\) wide. ### Step 2: Draw a Diagram Draw a diagram to visualize the situation. Label: - The width of the river as \(2 \, \text{km}\). ...
