Question

Which two statements can you use to distinguish between traveling west at 5 miles per hour and traveling east at 5 miles per hour without using the words “east” and “west”?

Answer 1

We can solve this by giving the velocities opposite signs.

Explanation:

Traveling west at 5 miles per hour can be given a positive sign and traveling east is opposite to west on a straight line, so we can denote that with a negative sign.

Hence, we can distinguish the velocities without using the words "east" and "west" by giving the velocities opposite signs.
