Rhonda is traveling from New York City to Paris and is trying to decide whether to fly via Frankfurt or to get a more expensive direct flight. Given that it is 3,857 miles from New York City to Frankfurt and another 278 miles from Frankfurt to Paris, what is the range of possible values for the direct distance from New York City to Paris?
Accepted Solution
A:
NYC TO FRANKFURT= 3857
NYC TO PARIS=X
FRANFURT TO PARIS=278
3857+278 > X
4135 > X
278+X > 3857
X > 3857-278= 3579
3857+X > 278
X > 278-3857= -3579
3579 < DISTANCE < 4135
