Question

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

Answer 1

Option B

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.
