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:
Ratio of speed of boat in downstream and speed of stream is 9:5, if speed of current is 10 km/hr, then find distance travelled (in km) upstream in 6 hours.
Ratio of speed of boat in downstream and speed of stream is 5:2, if speed of current is 4 km/hr, then find distance travelled (in km) upstream in 6 hours.
