Long John Silver, a pirate, has buried his treasure on an island with five trees located at the following points: A (30.0m, -20.0m), B(60.0 m, 80.0m), C (-10.0m, -10.0m), D (40.0m, -30.0m), and E(-70.0m, 60.0m). All of the points are measured relative to some origin. Long John's map instructs you to start at A and move toward B, but cover only one-half the distance between A and B. Then move toward C, covering one-third the distance between your current location and C. Then move toward D, covering one-fourth the distance between where you are and D. Finally, move toward E, covering one-fifth the distance between you and E, stop and dig. (a) What are the coordinates of the point where the pirate's treasure is buried?...after trying several formulas that I know and looking at the internet for help, I haven't been able to find an answer. If anyone can please help me it will be much appreciated.

0yes, but I don't know how that will help me find the points – 2011-09-11

0@mixedmath: You don't need the distance formula here; you can just take the given fractions of the vectors without calculating their lengths. – 2011-09-11

0@joriki: oh, you're absolutely right. I was busy thinking that this is just some computation, and I gave the wrong one. Very silly of me. Thank you. – 2011-09-11
