HallsofIvy, thank you so much.I think it's not complete or was cutted,idk.. About the 'knots' covered by the ships,hehe,well,that's what the reference book gives.. thank you so much. oh, sorry for the ' that i used in N30'W, that's actually degrees.i did not found the degree sign.hehe.im so sorry.

Please answer this, it's so hard. Problem: At 12 noon, ship A travels due west at 100 knotsshiop B. After 4hours, ship B leaves the same port on the direction N30'W at 80 knots. How fast is the distance between two ships changing at 8PM in the same day? Reply please.I can't solve it...
