1) Gathering the data
3 friends
Beth lives 4 blocks Ann
2) Let's sketch it
3) Let's do a number line
Since Ann's in position 0, and Beth is 4 blocks away, She might be at the right or at the left of Ann. Beth might be at point 4 or at the point -4. A for Carol 2 and -2.
Carol, can be always at halfway between Ann and Beth since She's only 2 blocks to the right or she can be 2 blocks to the left.
In the number line, The possible locations for Beth are point 4 and point -4 since 4 and -4 have the same absolute value, in comparison to zero. And Carol's place might be at point 2 or point -2.
