Question

You live in Worland, Wyoming, which has approximate latitude-longitude coordinates of (44 N, 88 W). Your friend lives in Portland, Maine, with coordinates of (44 N, 70 W). You plan to meet halfway between the two cities. What are the coordinates of the halfway point?

(44 N, 80 W)

(44 N, 78 W)

(44 N, 79 W)

(40 N, 79 W)

Answer 1

Okay, pretend we're in mathland. 
No N or W.
*groan or yay*
Here's the "formula" for points:
(x, y)

Now, the points are (44, 88) and (44, 70.)

Halfway?
We can see that the x-coordinates are the same, so we can just ignore that for a little bit.

88 and 70.

What's halfway between 70 and 88?
Well, 88-70 = 18.

Half of 18? 9.

Either subtract 9 from 88 or add 9 to 70. We get 79.

Now I said only ignore x for a LITTLE BIT, so we need to pay attention to it now.

(44 N, 79W)

Hope this helps! :P
