On the number line, 0 represents their starting point, negative values represent the distance traveled west and positive values represent the distance traveled east. All values are given in feet. A number line with a point for Lucas at coordinate 240 and a point for Karina at coordinate -240. How many feet apart are Karina and Lucas on the number line? Enter your answer in the box.

Answer 2

Answer: Karina and Lucas are 480 feet apart on the number line.

Explanation:

Since we have given that

A number line with a point for Lucas at coordinate 240.

A number line with a point for Karina at coordinate -240.

So, Number of feet that Karina and Lucas apart on the number line is given by

`240-(-240)\\\\=240+240\\\\=480\ feet`

Hence, Karina and Lucas are 480 feet apart on the number line.
