**drwls**, Friday, September 17, 2010 at 1:00pmThe west component of velocity is reduced becasue of the west wind to 155cos45 - 45 = 64.6 mph (relative to the ground).

The south component of speed remains 155 sin45 = 109.6 mph

The new ground speed is the hypotenuse:

sqrt[(109.6)^2 + (64.6)^2] = 127.2 mph
