Question

A train takes 2h to.Reach station b from station a and then 3h to.Return from station b to station a the distance between the two station is 200 km find the average speed

Answer 1

Answer:

velocity is 0

Explanation:

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 = 400%2F5

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
