Question
A man rows upstream 10 km and downstream 15 km
taking 5 hours each. Find the man’s speed in still water.Solution
Distance upstream = 10 km, time taken to row upstream = 5 hrs. Speed upstream = 10/5 = 2 km/hr. Distance downstream= 15 km, Time taken to row downstream = 5 hrs. Speed downstream = 15/5 = 3 km/hr. Man’s rate in still water = (3 + 2) * ½ = 2.5 kmph
