Explanation:

- Speed of Boat in Still Water: 144 km/hr

- Speed of Stream: 54 km/hr

- Effective Speed Upstream: \(144 - 54 = 90\) km/hr

- Effective Speed Downstream: \(144 + 54 = 198\) km/hr

- Difference in Time for Same Distance (Upstream vs Downstream): 0.2 hours

To find the distance:

- Let Distance = \(d\) km.

- Time Upstream = \( \frac{d}{90} \) hours.

- Time Downstream = \( \frac{d}{198} \) hours.

The equation for time difference according to the problem:

$$ \frac{d}{90} - \frac{d}{198} = 0.2 $$

Solving for \(d\):

- Equate and Solve:

$$\frac{d (198 - 90)}{90 \times 198} = 0.2$$

$$\frac{108d}{17820} = 0.2$$

$$108d = 3564$$

$$d = \frac{3564}{108}$$

$$d = 33 \text{ km}$$

- Option 1: 33 km

Correct Answer: 33 km
