The speed of a boat in still water is 12 km/h and the speed of the current is 3 km/h. A person travels 135 kilometers in a boat in the upstream direction and returns to the starting point in the downstream direction. Find the time taken to cover the entire journey.
Let the speed of boat in still water =B and speed of stream =S B=12km/h, S= 3km/h Speed of the boat in upstream =B-S=9km/h Speed of the of the boat in Downstream =B+S =15km/h ATQ- Total time = (135/9 +135/15) =15+9=24hours.
