Natural Bridge in VA is 215 feet above ground level while neary Luray Caverns is 260 feet below ground. Which two absolute value expressions could be used to find the distance between the top of Natural Bridge and the bottom of Luray Caverns?

• |215 - -260|

• |215 - 260|

• |-260 - 215|

Natural Bridge in VA is 215 feet above ground level while neary Luray Caverns is 260 feet below ground. The distance between the top of Natural Bridge and the bottom of Luray Caverns is _____ feet. (Just type the number).

Why do we use absolute value to solve these problems? Choose the best mathematically based answer.

• Just to make things complicated. There is no need.

• Distance between two points is always positive and using absolute value allows us to find the distance between the negative number and the positive number without getting a negative answer.

• Because the Commonwealth of VA SOL's may test us on this.
