A swimmer is capable of swimming at 1.65ms- in still water. If he swims directly across a 180m wide river with water flow at 0.85`ms^(-1)`', how far down stream will he reach? How long will it take to reach the other side ?

Explanation

To solve the problem step by step, we will break down the components of the swimmer's movement across the river and calculate the required values.

### Step 1: Identify the given values
- Speed of the swimmer in still water, \( V_s = 1.65 \, \text{m/s} \)
- Width of the river, \( d = 180 \, \text{m} \)
- Speed of the river current, \( V_r = 0.85 \, \text{m/s} \)

### Step 2: Calculate the time taken to swim across the river
