Answer:
D) 70
Step-by-step explanation:
Here is the correct mathematical way of find a distance between two points on the number line.
Take the absolute value of the difference of their coordinates.
If the points on a number line correspond to coordinates a and b, the distance between the points is
|a - b|
Your problem:
|a - b| = |-57 - 13| = |-70| = 70
The distance is 70.
