My son had an Algebra question he was unable to answer. We were also unable to locate an example in his book or on the internet.

The question is:
If a plane flew 200 km/hr one way and 300 km/hr for the return trip and the total trip took 6 hrs, how far did the plane go? Any help is appreciated.

I was up on a mountain at my brother's house in AZ one night and saw a huge creature that I looked up to be a windscorpion. It looks very like pics of Camelspiders from Iraqi desert. It looks like you crossed a spider and a scorpion and was about 4 or 5 inches, I guess about the width of my palm.

My fiance says that he thinks that insects in the desert are subject to extra solar radiation and it causes strange looking ones, such as they mutate into different forms faster.
Do you think this is so?

not sure if this apply to this but
U x v = 1
v squared = 2

projv u = 1/2 (0, 1, 1)
= (0, .5, .5 )

u - projvu = (1, 0, 1) - (0, .5, .5)
= 1 , -1/2, 1/2
