Question
The upstream speed of a motorboat is 14 km/hr. If the boat travels 256 km downstream in 8 hours, find the speed of the current.
Solution
Let the speed of the current be ‘x’ km/hr Therefore, speed of the boat in still water = (x + 14) km/hr According to the question, (x + 14 + x) = 256/8 Or, 2x + 14 = 32 Or, 2x = 18 Or, x = 9 Therefore, speed of the current = 9 km/hr
