Question

a train takes 2hrs to reach station B from station A and 3hrs to return back to A station A and B are separated by a distance of 400km what is the average speed and velocity of the train

Answer 1

solution.

Average speed= total distance travelled/total time taken.

=> 800/ 5

= 160 Km/h

Average velocity= displacement/time taken.

Here displacement is 0

so, 0/5= 0

So, average velocity= 0km/h
