Answer: true

Explanation: took the test

Answer 2

Average velocity is defined as the ratio of change in position to the time taken for that change.

Answer: True

Step-by-step explanation:

Velocity is obtained by dividing the displacement of an object by time interval. Displacement is a vector quantity which is defined as the shortest distance between initial and final point of an object.

In other words, displacement is the change in position of an object. A position-time graph can be plotted to find the average velocity of an object graphically. The average velocity can be obtained by calculating the slope of the position-time graph.

`v_av= \frac {change in position} {time taken for the change}`

While average velocity deals with velocity over a particular time interval, instantaneous velocity gives the velocity of an object at a particular point of time or instant.
