Question

Starting from the front door of your ranch house, you walk 60.0 m due east to your windmill, and then you turn around and slowly walk 40.0 m west to a bench where you sit and watch the sunrise. It takes you 28.0 s to walk from your house to the windmill and then 43.0 s to walk from the windmill to the bench. For the entire trip from your front door to the bench, what is your average velocity?

For the entire trip from your front door to the bench, what is your average speed?

Answer 1

Answer:0.281 m/s

Explanation:

Given

First person  walks 60 m east and it takes 28 sec

then he slowly turns to walk towards 40 m and it takes him 43 sec

$Average\ velocity =\frac{displacement}{time taken}$

$V_{avg}=\frac{20}{71}=0.281 m/s$

Thus average velocity during entire trip is 0.281 m/s.

Average speed will be different than average velocity as speed takes in account of distance.
