The average velocity of a car that travels 30 kilometers due west in 0.50 hour - 60 km/hour west.
Average velocity is the displacement of an object with the time change. To find the average speed of an object we divide the distance travelled by the time elapsed.
- Velocity is a vector quantity and average velocity can be found by dividing displacement by time.
- Average velocity is defined as the change in position or displacement (∆x) divided by the time intervals (∆t) in which the displacement occurs
Average velocity = ∆x/∆t
Then,
average velocity = 30/0.5
= 300/5
= 60
Thus, the correct answer would be - 60 km/hour west.
