Question

A man rows to a place 35 km
in distance and back in 10
hours 30 mintues. He found
that he can row 5 km with the
stream in the same time as he
can row 4 km against the
stream. Find the rate of flow of
the stream.​

Answer 1

Answer:

Let speed of man and stream is 'V', 'U'

Time5V+U=4V−U

[Travelling distance in same time]

5V−5U=4V+4U

V=9U

VU=91

Let U=x, V=9x

352x(15+14)=212

5x×920=3

x=34=0.75

Speed of stream

=1×0.75

=0.75 km/hr
