A man rows downstream 30 km and upstream 20 km. If he takes 5 hours to cover each distance, then the speed of stream is
- A \(5 km / hr\)
- B \(1 km / hr\)
- C \(4 km / hr\)
- D \(6 km / hr\)
Answer & Solution
Correct Answer
(B) \(1 km / hr\)
Step-by-step Solution
Detailed explanation
\( \text{Speed downstream} = \frac{30 \text{ km}}{5 \text{ hr}} = 6 \text{ km/hr} \) \( \text{Speed upstream} = \frac{20 \text{ km}}{5 \text{ hr}} = 4 \text{ km/hr} \) \( \text{Speed of stream} = \frac{\text{Speed downstream} - \text{Speed upstream}}{2} \)…
