If points A and B are located at \(-2.4\) and \(3.6\), respectively, on the number line, what is the length of segment AB?
Answer and explanation
Correct answer: \(6\)
The distance between two points on a number line is the absolute value of the difference of their coordinates: \(|3.6-(-2.4)|=|6|=6\). Therefore, the length of AB is \(6\). Remember that distance is always non-negative; \(1.2\) results from incorrectly subtracting the decimal parts only.
