I'm not sure what's an average time but a 51 second 400m is very good for a 16 year old. (Top in Ontario for sure).
The average velocity of a runner who completes one lap of a 400m track in 75 seconds is 5.33 m/s. This is calculated by dividing the distance traveled (400m) by the time taken (75s).
i am 13 and i got 57 for 400m
To find the average speed you divide the distance by the time. Use the formula v=d/t, v standing for velocity or speed, d standing for distance, and t standing for time. So, 400m/ 32s = 12.5m/s
Bolt has run 45.28s for 400m.
at my school its like a 50.5 or below for really good teams it can be as low as 48 or 49
Any time.
Well with proper hurdle technique you should be able to maintain a 1:03 or 1:04. Considering your probably a beginner I would expect your time to be a 1:09, 10 seconds slower than your 400m time.
