Question
A boat takes half time in moving a certain distance
downstream than upstream. What is the ratio between rate in still water and rate of current ?Solution
Let the speed of a boat in still water = ukmph And, speed of current = vkmph Rate downstream = (u+v) kmph Rate upstream =(u−v)kmph Let the distance covered in each case be x km. Then, (2x/u+v) = (x/u−v) 2(u−v) = u+v u = 3v (u/v) = 3:1 Therefore, Required ratio = 3:1
