**Given **that a particle moves on a line away from its initial position so that after t hours it is miles from its initial position.

We have to find the average velocity of the particle over the interval [1, 4].

As, **average velocity is the change is position over the change in time. **

∴

=

**Hence, average velocity is 32 miles/hr.**
