A man can row 8 Kmph in still water. If the velocity of the current is 2 Kmph and it takes him 2 hours to row to a place and come back. How far is the place
8 + 2 = 10 kmph
8 - 2 = 6 kmph
required distance be X km
Then X/10+X/6 = 2
3X + 5X = 60 8X = 60 X = 7.5 km
A man rows to a place 48 Km distance and back in 14 hours. He finds that he can row 4 Km with the stream in the same time 3 Km against the stream. The rate off the stream is
In a stream running at 2 Kmph, a motor boat goes 10 Km upstream and back again to the starting point in 55 minutes. Find the speed of motor boat in still water
A man can row 24 kmph in still water. It takes him thrice as long to row up as to row down the river. Find the rate of the stream?
