Question 821796
a man walks 500 m due east in 200 seconds and then 150 m due west in 50seconds calculate his average speed and his average velocity for the whole journey
:
Av Speed = total dist traveled / total time
s = {{{(500+150)/(200+50)}}}
s = 2.6 m/sec
:
Av velocity = Change in position / time
v = {{{(500-150)/(200+50)}}}
v = 1.4 m/sec
