Question

What value did Kerri find for the distance?

A.
–3714

B.
–3142

C.
3142

D.
3714

Answer 1

Ok, you're dealing with a 1 dimensional number line.

To find the distance between these two points what you want to do is go from -3428 to 0, then from 0 to 286.

The distance between -3428 and 0 is 3428. The distance from 0 to 286 is 286.

Add up both these differences:

3428 + 286 = 3714

So the answer is in fact D, 3714.
