What is distance between ( -7 ) and ( -19 )
Answer and explanation
Correct answer: 12
On a number line, the distance between two numbers is the absolute value of their difference: \(\lvert -7-(-19)\rvert=\lvert 12\rvert=12\). Therefore, the correct answer is 12. Values such as 11 or 13 result from subtracting incorrectly by one; they are not the actual difference. Exam tip: always express distance as a non-negative value.
