Question
A boat takes 28 hours for travelling downstream from
point A to point B and coming back to point C midway between A and B. If the velocity of the stream is 6km/hr and the speed of the boat in still water is 9 km/hr, what is the distance between A and B?Solution
Downstream speed = 9+6 = 15 Upstream speed = 9-6 = 3 Now total time is 28 hours If distance between A and B is d, then distance BC = d/2 Now distance/speed = time, so d/15 + (d/2)/3= 28 Solve, d = 120 km
