Answer
Here's how to calculate the average velocities:**Understanding Average Velocity**Average velocity is calculated by dividing the total displacement (change in position) by the total time taken. It's important to note that velocity is a vector quantity, meaning it has both magnitude (speed) and direction. Since you're both traveling to the same place, the direction is the same, so we only need to calculate the magnitude.**Calculations*** **Your friend's average velocity:** Distance = 250 km Time = 2 hours Velocity = Distance / Time = 250 km / 2 hours = 125 km/hour* **Your average velocity:** Distance = 250 km Time = 3 hours Velocity = Distance / Time = 250 km / 3 hours = 83.33 km/hour (approximately)**Answer:**Your friend's average velocity is 125 km/hour, and your average velocity is approximately 83.33 km/hour.
