Question

what is the distance between -25 and 15 on a number line?
units

Explanation:

Step1: Recall distance formula

The distance between two numbers \(a\) and \(b\) on a number line is \(|a - b|\) (absolute value of their difference).

Step2: Substitute values

Let \(a=-25\) and \(b = 15\). Then the distance is \(|-25-15|\).

Step3: Simplify the expression

First, calculate \(-25 - 15=-40\). Then take the absolute value: \(|-40| = 40\).

Answer:

40
