Answer:
2.6 units
Explanation:
Point A lies between -2 and -1. Segment [-2,-1] is divided into 10 equal parts, this segment has length of 1 unit, so each part has length of 1/10 = 0.1. Point A lies three such parts to the left from -1, thus its position is
-1 - 0.3 = -1.3
Point B lies between 1 and 2. Segment [1,2] is divided into 10 equal parts, this segment has length of 1 unit, so each part has length of 1/10 = 0.1. Point B lies three such parts to the right from 1, thus its position is
1 + 0.3 = 1.3
The distance between A and B is
