**Reiny**, Saturday, June 19, 2010 at 8:06pmspeed of the plane without wind --- x mph

speed of the wind ---- y mph

time with wind :

4(x+y) = 768

x + y = 192

time against wind:

6(x-y) = 768

x-y = 128

add them

2x = 320

x = 160

then 160+y = 192

= 32

windspeed = 32 mph

check: speed with wind = 160+32 = 192 mph

time to go 768 = 768/192 = 4

speed against wind = 160-32 = 128

time against wind = 768/128 = 6
