Answer:

3579  <  x  <  4135

Step-by-step explanation:

What is Given:

NYC to FrankFurt = 3857

FrankFurt to Paris = 278

--------------------------------------------------

Soloving For:

NYC to Paris.

(x = distance for NYC to Paris)

3857 + 278 > x

                         (3857 + 278 = 4135)

4135 > x

x + 278 > 3857

   -278     -278

---------------------------

x > 3579

(You need to subtract 278 from both sides to cancel them out)

x + 3857 > 278

   -3857    -3857

----------------------------

x > -3579

(Because this is a negative number, this this not really useful in helping us find the distance range.)

So the range is 3579 < x < 4135
