Points c and d are 884884 statute miles apart. how far apart are c and d in nautical miles? assume the radius of the earth at the equator is approximately 3956 statute miles.

I think this problem gave the data for the radius of earth so that we will know the conversion ratio between statute miles and nautical miles. However, you can simply search that. There are 1.15 statute miles in 1 nautical mile. Hence,

Distance in nautical miles = 884884 statute miles * 1 nautical mile/1.15 statute miles
Distance =769,464.35 nautical miles

The answer simplified would be. -6300x

Ithink the right answer could be 50%
