Question

Which equation would you use to find the distance between the two points?

A. |-6 - 5|
B. |6 - 5|
C. |6 - (-5)|
D. |-6 + 5|

Answer 1

it's C because |-6 - 5| can be simplified to |6+5| which is |11| therefore, the distance is 11 blocks.

Answer 2

The answer is C


Displacement is a vector quantity so it may be either positive or negative. As per convention, acceleration taken as positive when moves downward direction. But, in our case, acceleration towards downward taken as negative, so displacement should also be negative because negative sign only indicate its downward direction.
