Question
A boat has a speed of 30 km/h in still water. In a
particular stream, the boat's downstream speed is 50% faster than its speed upstream. What is the speed of the stream?Solution
Let the speed of the stream = 'k' km/h Then, upstream and downstream, speed of the boat are (30 - k) km/h and (30 + k) km/h, respectively According to the question, 30 + k = (30 - k) X 1.5 Or, 30 + k = 45 - 1.5k Or, 2.5k = 15 So, k = 6 Therefore, speed of the stream = 6 km/h
