**Problem: The distance a person can walk in time**.

*t*is given by d=√t where*d*is measured in miles and*t*is measured in hours**A)**Find the average velocity from

*t*=1 to

*t*=4.

**B)**Estimate the person's velocity at

*t*=4 hours.

The answers to the problem are:

A) 1/3 MPH

B) 0.25 MPH

## Homework Equations

Velocity=distance/time

**Ending words:**

So if anyone can show me the steps on solving this problem for both parts A and B, it would be greatly appreciated to not just me, but my knowledge itself...

Thanks in advance,
