You walk for 6.44 km with at a constant velocity of 2.54 m/s due west, turn around, and then walk with an average velocity of 0.480 m/s due east. from your starting point to your destination, your overall average velocity is 1.35 m/s due west. during the trip, how far east did you walk?

Respuesta :

Kalahira
Time taken to walk west = 6440m/2.50m/s =2576s
 
Let t be the time taken to travel east and x be the distance travel towards east x= 0.435m/s * t -(1)

Since Average overall velocity
 = total displacement/ total time
 1.20m/s=(6440-x)/(t+2576s) -(2)
 
Now you have gotten two simultaneous equation, resolve them and you will get x=883m
