Answer:0.281 m/s
Step-by-step 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 =(displacement)/(time taken)](https://img.qammunity.org/2020/formulas/physics/college/6pd143punhprzos1jo09xkq573ijac9qax.png)
![V_(avg)=(20)/(71)=0.281 m/s](https://img.qammunity.org/2020/formulas/physics/college/cf3ox6wi5wpn6em4g75mz7y57wpf5citds.png)
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.
