A train takes 2 hours to reach station b from station a,
and then 3 hours to return from station b to station a.
The distance between the stations is 200 km.
Find the (a) average speed
let a = average speed, it took 5 hrs to travel 400 km
a =
a = 80 km/hr
:
(b) average velocity of the train.
Velocity involves direction and displacement
Since it ended up in the same place it started (A); velocity is 0
