Question
The ratio of the speed of the stream to the speed of the
boat in still water is 3:7. If a distance of 280 km is covered downstream in 4 hours, determine the time required to cover the same distance upstream.Solution
Let the speed of stream and speed of boat in still water be 3x and 7x. When it travels downstream Then 3x+7x = 280/4 10x = 70 X = 7 time taken to cover same distance by upstream = 280/(7x-3x) = 280/28 = 10 hours
