Best ResponseYou've already chosen the best response.0let the age of captain be x , and the age of the ship be y , say let some z years before the captain be as old as the ship is now. this means xz=y; but the captain is old as the age of the ship z years back , ie x=2(yz); and x+y=56 ,now solve for x =44.8

Best ResponseYou've already chosen the best response.0you got the equasions right, but with them came to the wrong answer. If x=44.8, then y must be 5644.8=11.2 and z must be xy=33.6. Z years ago the thip was not built yet.
