What is distance between ( -45 ) and ( -15 )
Answer and explanation
Correct answer: 30
The distance between two numbers on a number line is the absolute value of their difference: \(\left|-45-(-15)\right|=\left|-30\right|=30\). Therefore, the correct answer is 30. \(-30\) can be the signed difference, but distance can never be negative. Exam tip: always take the absolute value when finding distance.
