Tai ran from his home to a position 300 m south of his home in 100 seconds. what was his velocity? a 3 m/s north b 0.33 m/s north c 0.33 m/s south d. 3 m/s south answer is 3 m/s is correct but which answer is south or north?

Well, if you are moving forward in a direction, then your velocity is your speed with the direction you are moving in. To calculate velocity, you divide your distance traveled by the time it took to travel that distance and you add your direction to it.
So to conclude, 300/100= 3 m/s South
