How could you distinguish between traveling west at 5 miles per hour and traveling east at 5 miles per hour without using the words "east" and "west"?

the two examples are different because they not traveling in the same direction but still they travel the same distance within the same amount of time and will most likely lead to different areas

We can solve this by giving the velocities opposite signs.

Step-by-step 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.

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
