What is the distance between the points 0 and 3 on the number line?
Answer and explanation
Correct answer: 3 units
The distance between two numbers is the absolute value of their difference: |3−0|=3 units. Therefore, the correct answer is 3 units. −3 may represent directed displacement, but it cannot represent distance because distance is always non-negative. Exam tip: On a number line, subtract the smaller number from the larger number to find the distance.
