Question
Speed of a boat in still water is 9 kmph and speed of
stream is 6 kmph. A man rows to a place at a distance of 30 km and come back to starting point. The total time taken by him is:Solution
Rate upstream = 9 – 6 = 3 kmph Rate downstream = 9 + 6 = 15 kmph Time taken to go upstream = 30/3 = 10 hr Time taken to go downstream = 30/15 = 2 hr Total time = 10 + 2 = 12 hrs
