To find George's velocity in meters per second, we need to calculate his displacement and divide it by the time taken.
First, let's determine George's displacement. Displacement refers to the distance and direction between the starting point and the end point. In this case, George's starting point is not mentioned, but we know that he ends up 500 meters north. So, his displacement is 500 meters north.
Next, we need to calculate the time taken. Unfortunately, the time is not provided in the question, so we don't have enough information to calculate the exact velocity. However, the answer provided assumes a time of 13 seconds. So, we'll use that value for the calculation.
Finally, we can calculate George's velocity. Velocity is equal to displacement divided by time. So, in this case, the velocity would be 500 meters north divided by 13 seconds, which equals approximately 38.46 meters per second.
It's important to note that the actual value for George's velocity may differ depending on the actual time taken, which is not provided in the question. But based on the assumption of 13 seconds, the answer would be 38.46 meters per second.
