Question
The speed of a boat upstream is 10 km/hr. If it travels
210 km downstream in 7 hours, what is the speed of the current?Solution
Let the speed of the current be āxā km/hr Therefore, speed of the boat in still water = (x + 10) km/hr According to the question, (x + 10 + x) = 210/7 Or, 2x + 10 = 30 Or, 2x = 20 Or, x = 10 Therefore, speed of the current = 10 km/hr
