Answer:
The equator has the length:
- C = 2πr, where π = 22/7, r = 6400 km
- C = 2*22/7*6400 = 40228.57 km (rounded)
a) Consider X and Y as two points on the circle with C = 40228.57 km.
The distance between X and Y is:
- d = C*(123 - 67)/360
- d = 40228.57*56/360 = 6257.78 km (rounded)
b) Since both X and Y are on the equator, they are at the same distance from the north pole, N.
NX makes 90 degrees:
- NX = C*90/360
- NX = 40228.57*1/4 = 10057.14 km (rounded)
