i have posted this question up alot of times before but i guess no one gets it because no one ever replies..
find the latitude of Spokane, WA if Spokane and Jordan Valley, OR, 43.15degN, are 486 km apart.
(assuming that the cities lie on the same norht-south line and that the radius of the earth is 6400 km.)
my choices are
A. 47.50degN
B. 38.80degN
C. 52.46degN
D. 39.50degN
i drew this whole problem out and i crossed out C and D from my answer choices...i think its A or B but im not sure which one

Along a north-south meridian, one degree is about 70 miles or 112 km. 486 km is thus 4.3 degrees.

4.33 + 43.15 = 47.48 degres

Pick option (a)
