A man rows a certain distance downstream in 5 hours and back to the same point in 8 hours. If the speed of the stream is 4.5 km/hr then what is the spee...
A man can row 25/2 km an hour in still water and he finds that it takes him thrice as long to row up as to row down the river. The rate of stream is:
A boat can cover 150 km in downstream in 15 hours and 120 km in upstream in 12 hours. Find the distance travelled by the boat in still water in 5 hours.
A boat running downstream covers a distance of 24 km in 3 hrs while it covers the same distance upstream in 6 hrs. Then speed of the boat in still water is
