It takes a ship 3 hours to cover 72 km with the current and 4 hours against the current. Find the speed of the ship in still water and the speed of the current.

Answer 1

s + c = 72 / 3

s - c = 72 / 4

add the equations (to eliminate c)

solve for s

substitute back to find c

Answer 2

s = 21 km/h
c = 6 km/h
