Average speed is the total distance covered by total time taken.
Here the total distance covered is 90 + 90 = 180m
So average speed = 180m/60s
= 3m/s
Average velocity is the displacement by time taken
Here displacement = 90-90 = 0
So, average velocity is 0m/s
Here the total distance covered is 90 + 90 = 180m
So average speed = 180m/60s
= 3m/s
Average velocity is the displacement by time taken
Here displacement = 90-90 = 0
So, average velocity is 0m/s
NihaGiha:
do u have any other question
an electric train is moving with a velocity of 120 km per hour how much distance will it move in 30 seconds
Convert 120km/hr into m/s
then multiply by 30
u will get the answer
Have u Understood?
mark it as brainliest
I have marked
thanks,
welcome

@
Average speed = distance / time
=(180/60)m/s
=3m/s
Average speed of ramu = 3 m/s
______________________
Average velocity = displacement / time
=0/60
=0
Average velocity of ramu = 0 m/s
