QUESTION: A truck travels 250 km West in 6.0 h. Find the velocity.
-----------------------------
FORMULA: velocity = [tex]\frac{displacement}{time}[/tex]
SUBSTITUTION: velocity = [tex]\frac{250 km}{6 hrs}[/tex]
ANSWER: 41.67 km/h West
- estimated to the nearest hundredths
- original answer: 41.66666666...
--------------------------------

2) Displacement
- It refers to the shortest distance between the final and initial position of the object with consideration to a reference point. This is a vector quantity of distance, meaning it has both magnitude and direction.
3) Vector Quantity
- This kind of quantity expresses both magnitude and direction.
- For example, a truck is going 300 km South.
