Question
A boat goes 240 km downstream in 12 hours, and 160 km
upstream in 16 hours. The speed of the stream is ÂSolution
Distance downstream= 240 km Time taken to row downstream = 12 hrs. therefore, speed downstream = 240/12 = 20 km/hr Distance upstream = 160 km Time taken to row upstream = 16 hrs therefore, speed upstream = 160/16 = 10 km/hr therefore, speed of the stream = 1/2 (20 - 10) = 5 km/hr
