What is distance between ( -12 ) and ( -20 )

Answer and explanation

Correct answer: 8

On a number line, the distance between two numbers is the absolute value of their difference: \(|-12-(-20)|=|-12+20|=|8|=8\). Therefore, the correct answer is 8. A value such as 7 can result from an incorrect subtraction, and distance can never be negative. Exam tip: always use \(|a-b|\) to find the distance between two numbers.
