Question

Which of the following expressions represents the distance between -3.9 and -4.7

Answer 1

None of the above

Explanation:

Distance is the difference between two positions. That is x1- x2 Since both numbers were negative, you would want the absolute value of one plus the other, because subtracting a negative results in a positive. For this example the distance would look more like this:

| -4.7 - ( -3.9 ) | = .8
