I don't rember exactly the question.
its about average velocity.
A person travel 400 meter, he complete 4 ROUNDS at 60 sec,57SEC,55SEC AND 53 sec.what if average velocity?
isnt average velocity total distance/total time?
yes,it seems to average velocity,
To calculate average velocity, you need to divide the total displacement by the total time taken. In this case, the total displacement is the distance traveled, which is 400 meters. The total time taken can be found by adding up the individual times for each round.
First, convert all the times into seconds:
60 sec = 60 sec
57 sec = 57 sec
55 sec = 55 sec
53 sec = 53 sec
Now, calculate the total time taken by adding these individual times:
60 sec + 57 sec + 55 sec + 53 sec = 225 sec
Next, plug the values into the formula for average velocity:
Average Velocity = Total Displacement / Total Time Taken
Average Velocity = 400 meters / 225 sec
= 1.78 meters per second (rounded to two decimal places)
Therefore, the average velocity of the person is approximately 1.78 meters per second.
