Ravi's speed of rowing in still water is 6 km/hr
The speed of the stream is 3 km/hr
He rows between two points in a river and returns to the same point
He took 30 minutes more to cover the distance upstream than downstream
Find the distance between the two points
- A 3.53 km
- B 2.25 km
- C 5.12 km
- D 1.57 km
Answer & Solution
Correct Answer
(B) 2.25 km
Step-by-step Solution
Detailed explanation
\(v_d = 6 + 3 = 9\) km/hr \(v_u = 6 - 3 = 3\) km/hr \(\frac{D}{3} - \frac{D}{9} = 0.5\) \(\frac{3D - D}{9} = 0.5\) \(\frac{2D}{9} = 0.5\) \(D = \frac{0.5 \times 9}{2} = 2.25\) km
