- 6 kmph
- 6.5 kmph
- 9.5 kmph

Answers

S(u)(x-y)=2.5
Speed of man in still water is 6km/hr
6-y=2.5
Y=3.5km/hr(stream speed)
S(d)=x+y
6+3.5=9.5km/hr

The right answer is

The answer is
x=6
S(u)=2.5
S(u)=x-y by substititing x and S(u) we get y=3.5
then S(d)=9.5
To calculate current stream the formula
downstream-upstream=2(current)
9.5-2.5=2(current)
current stream=3.5 is the answer
