Step-by-step explanation:

Answer 2

Answer:

let speed of boat in still water =xkm/hr

let speed of stream=ykm/he

speed of downstream=x+y km/hr

speed of upstream=x-y km/hr

16/x-y + 24/x+y=6 eq. 1

12/x-y +36/x+y= 6. eq.2

let x-y= a

x+y = b

from eq. 1 16a+24b=6

12a+36b= 6

you can solve these equations by any method you get values of a and b then put the values you get x and y
