Question
A man rows upstream 16 km and downstream 24 km taking 8
hours each. Find the man’s speed in still water.   ÂSolution
Distance upstream= 16 km, time taken to row upstream = 8 hrs. Speed upstream = 16/8 = 2 km/hr. Distance downstream= 24 km, Time taken to row downstream = 8 hrs. Speed downstream = 24/8 = 3 km/hr. Man’s rate in still water = (3 + 2) * ½ = 2.5 kmph
