how many miles is it from Houston to Washington D.C. as the crow flies???

Answer 1

If the crow flies using Google Earth, it's 1,220.91 miles.

Answer 2

I won't do this problem using pencil & paper because I don't want to spend the time right now. But the idea is that if you pass an imaginary plane through Houston, Washington, and the center of the earth, you'll be marking off the "great circle" -- the shortest distance -- between those cities. You need to find the "central angle" between the cities at the center of the earth. Then you just multiply that angle (in radians) by the radius of the earth (3960 miles) to get the distance as the crow flies.

Getting that central angle is the hardest part, but you can do it, given latitude & longitude of both cities, and using some trigonometry and something called the "dot product" (a math formula).

Answer 3

are you really looking "as the crow flies", or are you looking for a perfect linear route, say "as the mole digs?" If so, you'd need to account for the suface curvature of the earth.

Answer 4

1390

Answer 5

Just as a side note, Which Houston? Houston, Texas --Houston, Tenn.--Houston, Ms-- or Houston Ca or ?????
