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 as 3 km against the stream. The rate of the stream is:
- 6 km/h
- 5 km/h
- 4 km/h
- 1 km/h
- d
-
Suppose he move 4 km downstream in x hours. Then,Speed downstream =(x4) km/hrSpeed upstream =(x3) km/hr∴(4/x)48+(3/x)48=14 or x=21So, Speed downstream = 8 km/hr, Speed upstream = 6 km/hr.Rate of the stream =21(8−6)km/hr=1km/hr
