What is distance between ( -30 ) and ( -10 )
Answer and explanation
Correct answer: 20
On a number line, the distance between two numbers is the absolute value of their difference: \(\lvert -30-(-10)\rvert=\lvert -20\rvert=20\). Therefore, the correct answer is 20. \(-20\) can be a signed difference, but distance can never be negative. Exam tip: always take the absolute value of the difference when finding distance.
