You walk for 6.44 km with at a constant velocity of 2.55 m/s due west, turn around, and then walk with an average velocity of 0.440 m/s due east. From your starting point to your destination, your overall average velocity is 1.33 m/s due west. During the trip, how far east did you walk?

Answer 1

V = -2.55 + 0.440 + x.
-1.33 = -2.11 + x, X = 0.78 m/s Due East.

d = V*T, 6440 = (-1.33)*T, T = -4842 s. = 4842 s., West.

0.78m/s * 4842s. = 3777 m., East.
