Question
A boat takes 14 hours to travel downstream from point P
to point Q and then return to point R, which is located halfway between P and Q. If the speed of the stream is 8 km/h and the boat's speed in still water is 12 km/h, find the distance between points P and Q.Solution
Downstream speed = 12 + 8 = 20kmph Upstream speed = 12 – 8 = 4kmph Distance between P and Q = x km x/20 + (x/2)/4 = 14 x = 80km
