Question

A cruise ship travels 300 miles due east. It travels 175 miles along it's new course. How far is the cruise ship from it's initial position?

Answer 1

The answer depends on where the ship starts from. If it starts on the equator, the answer is 459.938 miles.
If it starts at 70° N, then the distance is 446.084 miles.
And if the ship is on a flat earth, the distance is 459.954 miles (very close to the distance on a round Earth starting at the equator). Hope this helps!
