Question

On a number line what is the distance between -3/2 and 6?

Answer 1

15/2 or 7.5

Explanation:

Distance = x_2 - x_1

Distance = 6 - (-3)/2

Distance = 6 + 3/2

Distance = 12 + 3/2

Distance = 15/2 or 7.5

Answer 2

• 7.5 units

Explanation:

The distance is always positive and is same as the absolute value of subtraction of the two numbers on the line.

This can be shown as:

• |-3/2 - 6| =
• |-1.5 - 6| =
• |-7.5| =
• 7.5

or

• | 6 - (-3/2)| =
• |6 + 1.5| =
• |7.5| =
• 7.5
