Question

David's house is 12,000 feet due east of his business. If his house is assigned the position of zero and his business is assigned the position of +12,000, what would David's position be if he walked 1,000 feet east of his house?

Answer 1

If David's house is assigned the position of zero (0), then walking 1,000 feet east of his house would mean adding 1,000 feet to the position of his house. Therefore, his position would be:

0 (his house) + 1,000 feet = +1,000 feet.

So, David's position after walking 1,000 feet east of his house would be +1,000 feet.
