Question

On a number line, find the midpoint of a segment with the following endpoints:
A = -10 and B = 20
1) 10
2) 5
3) 12
4) 5.5

Answer 1

-10-----------0----------------------20
midpoint ????

-10----------0-----5---------------20

distance from -10 to 20 on the number is 20-(-10) =30 mid point is 30/2=15
units from either end.

-10+15=5
20-15=5

Looks like it is a 5. Choice 2). Is that what you come up with also?
