Answer 1

Answer:

let x=speed of sailboat in still waters

let c=speed of current

x+c=speed of sailboat with the current

x-c=speed of sailboat against the current

travel time*speed=distance

...

3(x+c)=30

5(x-c)=30

..

3x+3c=30

5x-5c=30

..

15x+15c=150

15x-15c=90

add

30x=240

x=8

3c=30-3x=30-24=6

3c=6

c=2

speed of sailboat in still waters=8 km/hr

speed of current=2 km/hr
