George P$.$ Burdell is developing his first video game, The Phantom Scholar, which is $2$D with

continuous movement and runs at $30$ frames per second $($best effort$).$

In the game, there is an enemy which George intends to chase the player at $1\frac{m}{s}.$

Each frame of the game simulation, George computes the relative vector $)$ from enemy

$($position E$)$ to player $($position $P)$ like so:

$V=E-P$

Then he computes the updated position $(E_{\text{n}\text{e}\text{w}})$ with the following equation:

$E_{\text{n}\text{e}\text{w}}=E+V*\frac{1}{30}$

What problems will George likely observe with his implementation?

The enemy will stand in place, never moving.

The enemy will move away from the player instead of towards.

The enemy's velocity will not be at the target speed.

The position displacement of the enemy is not adjusted for variation in frame rate.

The enemy will circle around the world origin but never move more than $1$ m away from the origin.
