You are walking on a moving sidewalk (moving at a speed of 2 mph).if you are walking in the same direction as the sidewalk at a speed of 4 mph what is your velocity relative to the ground what would be your velocity if you were walking in the opposite direction as the moving sidewalk

I'd but I think it would be 2?

6 with, 2 against

To calculate your velocity relative to the ground, you need to consider both your own walking speed and the speed of the moving sidewalk.

In the given scenario, you are walking in the same direction as the moving sidewalk, which means your velocities will add up. So, your velocity relative to the ground will be the sum of your walking speed and the speed of the moving sidewalk.

Let's calculate:

Your walking speed = 4 mph
Speed of the moving sidewalk = 2 mph

Velocity relative to the ground = Your walking speed + Speed of the moving sidewalk
Velocity relative to the ground = 4 mph + 2 mph
Velocity relative to the ground = 6 mph

Therefore, if you are walking in the same direction as the moving sidewalk, your velocity relative to the ground would be 6 mph.

Now, let's consider the scenario where you are walking in the opposite direction as the moving sidewalk.

In this case, your velocities will subtract because you are moving in opposite directions. So, your velocity relative to the ground will be the difference between your walking speed and the speed of the moving sidewalk.

Let's calculate:

Your walking speed = 4 mph
Speed of the moving sidewalk = 2 mph

Velocity relative to the ground = Your walking speed - Speed of the moving sidewalk
Velocity relative to the ground = 4 mph - 2 mph
Velocity relative to the ground = 2 mph

Therefore, if you are walking in the opposite direction as the moving sidewalk, your velocity relative to the ground would be 2 mph.
