1.	the speed of the boat in still water is 8km/hr.If it takes the same time in going 20km downstream as it takes in going 12km upstream,find the speed of the water
Answer» Let the speed of water in the river be x km/hr Speed of boat upstream = (8 – x) km/hr Speed of boat downstream = (8 + x) km/hr Distance travelled downstream = 20 km Recall that TIME taken = (Distance)/(Speed) Time taken to travel downstream = 20/(8 + x) Distance travelled upstream = 12 km Time taken to travel upstream = 12/(8 – x) Given time taken to travel downstream = time taken to travel upstream Thus speed of water in the river is 2 km/hr.
