Find the distance in km between the following pair of cities, assuming they lie on the same north-south line. the radius of the earth is approximately 6400 km.

city a, 35° n, and city b, 22° s

35+22 = 57 degrees between the two cities
The arc distance between them is radius x angle
Convert 57 degrees to radians is 57*Pi/180 = .995
Then 6400*.995 =6367 km.

29. because you will divide each number of months by 12 to find the number of years. which would mean, 5, 12.5, 16, 45, 50, 72.5. which is crazy. anyhow, i think you find the median in the middle. and yea hope your test goes good
