Select the expression that represents the distance between the numbers r and p

Answer:
Option B
Step-by-step explanation:
Let's understand this problem in a simpler way,
If two points P and R represent the numbers as,
P = 2 and R = - 4
Then distance between these points will be,
P - R = -4 - 2 Or R - P = 2 - (-4)
= -6 Or R - P = 6
= ±6
But the distances are always positive so 6 will be the answer.
That's why we represent the distances between two points as,
|P - R| (Absolute value of the difference)
Option B is the answer.
