text: using the pythagorean theorem, you would be sqr((35^2)+(65^2)) Kilometers\n\nshown here:\n\nT=sqr((35^2)+(65^2))\nT=sqr(1225+4225)\nT=sqr(5450)\nT=73.824 Km\n\ngot it?\n\n//edit//\ngarypopkin has a good point\nbut i'll assume this is likely for a HS math course\nand of all probability, its not asking for much more than plane vectors\nlemme know if its the asking for the earth's surface: its much more complicated, but still possible
