Clockwise 90 is the same as counterclockwise 270. Since 270+90=360, going 270 degrees one way is the same as going 90 degrees the other way.

hat is the approximate distance between Portland, Oregon (45° north, 122° west), and San Francisco, California (37° north, 122°

juin [17]

Since both places are on the same longitude (122° west) and different lattitudes 45° north and 37° north, the distance between the two place lies on a great circle (along a line of longitude). Difference in latitudes = 45 - 37 = 8° (subtract the lattitudes because both sides are on the same side in the latitude i.e. both are north) The distance between two points along the line of longitude is given by theta / 360 x 2 x pi x R: where theta = 8° and R is the radius of the earth = 3,960 miles. d = 8 / 360 x 2 x pi x 3960 = 552.9 miles
