Air speed and ground speed are two different animals.
For instance, if you are in a car going 60 mph you are going 60 mph.
If you are in a plane and the speedometer read 60 mph (actually knots), you are only going 60 if there is no wind
. Your ground speed and air speed are the same. If you have a 20 mph head wind your ground speed is 40.
So you might think you're going to travel 60 miles in 60 minutes, but you're not.
