A man rows upstream 36 km and downstream 51 km taking 3 hours each. Find the man’s speed in still water.
Distance upstream= 36 km, time taken to row upstream = 3 hrs. Speed upstream = `36/3` =12 km/hr. Distance downstream= 51 km, time taken to row downstream = 3 hrs.
Speed downstream = `51/3` = 17 km/hr.
Man’s rate in still water = `1/2` (17+12) kmph = 14.5 kmph
