1. The problem statement, all variables and given/known data Suppose your location has a latitude of 43 degrees and the circumference of the Earth is 40,000 km. Measure the distance from your location along a circle. How far would you have to travel if you go a) to the equator, and b) to the North Pole 2. Relevant equations 3. The attempt at a solution For part "a" I got about 4,777 km. But not sure how to go about part "b". I need the a new latitude but not sure how to get it. I originally thought about subtracting 43 degrees form 360 degrees, but that seems way too big as it's the whole circumference of the Earth minus the portion from problem "a". Please see attached image. I need to find angle NOT I think.
