Question

A train takes 2 hours to reach station B from station A,and then 3h to return from station B to station A. The distance between the two stations is 200km. Find the average speed,average velocity

Answer 1

Speed=distance traveled/time taken

so average speed=(200+200)/(2+3)

=400/5

Average speed=80kmph

Also velocity=displacement/time

Since the train came back to its original position the displacement=0

.°. velocity=0/5=0.
