What is distance between 1/2 and -3/2
Answer and explanation
Correct answer: 2
The distance between two numbers on a number line is the absolute value of their difference. Thus, \(\left|\frac{1}{2}-\left(-\frac{3}{2}\right)\right|=\left|\frac{4}{2}\right|=2\). Therefore, the correct answer is 2. While \(-2\) may arise as a signed displacement in some order, distance can never be negative. Exam tip: always use absolute value when finding distance on a number line.
