Question
A boat goes 200 km downstream in 50 hours, and 90 km
upstream in 30 hours. Find the speed of the boat in still water isSolution
Distance downstream= 200 km Time taken to row downstream = 50 hrs. therefore, speed downstream = 200/50 = 4 km/hr Distance upstream = 90 km Time taken to row upstream = 30 hrs therefore, speed upstream = 90/30 = 3 km/hr therefore, speed of the boat in still water = 1/2 (4 + 3) = 3.5 km/hr
