OPTION B - 3,9
OPTION C - 9,3
OPTION D - 7.5,4.5


please give the solution for this question​

Answer 1

Answer:

Option C 9,3

Step-by-step explanation:

Let the speed of man be xkm/h in still water and boat be y km/h.

speed downstream= x+y=12 -(i)

speed upstream= x-y = 6 -(ii)

By solving Both the eqns.

we get,

2x=18

x=9.

putting x value in (i)eqn. we get,

y=3

so speed of man in still water= 9km/h

and speed of water is 3 km/h
