Calculate the average velocity of Joe is he was able to travel 40 km south in 2 hours in his car
avg vel=distance/time=40,000m/(120min*60sec/min)=40000m/7200sec
= 400/72=200/36=100/18=50/9 m/s
29
To calculate the average velocity, divide the total distance traveled by the total time taken. In this case, Joe traveled 40 km south in 2 hours.
Average velocity = Total distance / Total time
Average velocity = 40 km / 2 hours
Therefore, the average velocity of Joe's car is 20 km/hour.
