Please help me 

(a) Consider two points on the equator at coordinates (latitude, longitude) of (0°N, 20°E) and (0°N, 40°W). What is the surface distance between these two points, measured in km? Express your answer to 4 significant digits. ANSWER: (b) Consider two points with the same longitudes as in part (a) but at latitude 45°N. What is the surface distance between these two points? Express your answer to 4 significant digits.
Transcribed Image Text:(a) Consider two points on the equator at coordinates (latitude, longitude) of (0°N, 20°E) and (0°N, 40°W). What is the surface distance between these two points, measured in km? Express your answer to 4 significant digits. ANSWER: (b) Consider two points with the same longitudes as in part (a) but at latitude 45°N. What is the surface distance between these two points? Express your answer to 4 significant digits.
(c) Now consider two points on the same meridian of longitude, but with different latitudes, specifically (20°N, 127°W) and (30°N, 127°W). Determine the surface distance between these points. Express your answer to 4 significant digits. ANSWER: (d) Would your answer to part (c) be different if the points were (50°N, 127°W) and (60°N, 127°W)? If so, by how much? ANSWER: (e) Would your answer to part (c) be different if the points were along longitude 12°E instead of 127°W? If so by how much? ANSWER:
