The other thing that I only had a little trouble with was in investigation 2 ACE. It was the problem with the airplanes flying back and forth between NYC and San Francisco. It got confusing because of the winds going against the planes and seeing how long it took them fly a certain distance instead of how far they could get in a certain amount of time like in the prior week’s POW.

It is not confuysing if you think of it this way:

If the plane is going 100 miles and hour, and the winds are 20 miles an hour going to sanfrancisco, and 10 miles an hour going to NYC, than the equations for these would be simple:

NYC: 100-10
San Fran: 100-20
