**Reiny**, Thursday, September 23, 2010 at 8:07amplane -- x

wind -- y

960/(x-y) = 10/3 (#1)

960/(x+y) = 2.5 (#2)

#1

2.5(x+y) = 960

5x+ 5y = 1920

#2

10/3(x-y) = 960

10x+10y = 2880

2(#1)

10x + 10y = 3840

#2 : 10x-10y = 2880

add them

20x = 6720

x=336

sub back in simplest #1

5(336) + 5y = 1920

y = 48

check:

with wind: 960/(336+48) = 2.5

against: 960/(336-48) = 10/3 ... YEAH
