What is distance between ( -40 ) and ( -20 )
Answer and explanation
Correct answer: 20
The distance between two numbers on a number line is the absolute value of their difference: \(\lvert -40-(-20)\rvert=\lvert -20\rvert=20\). Therefore, the correct answer is 20. \(-20\) is the signed difference, not a distance, because distance cannot be negative. Exam tip: Always use the absolute value of the difference when finding distance.
