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).
That depends on your definition of fit and the athletes at question. For example, if the 400m runner is Jeremy Warner and the half marathoner is an overweight man that only trains 3 days a week, the 400m runner would be much fitter. In general a half marathoner will be much fitter than a 400m runner in aerobic fitness but slightly weaker in anaerobic fitness. So it depends what your definition of fit is. I am a long distance runner, so my opinion is biased, but I believe that a half marathoner is fitter than a 400m runner for many reasons. Usually long distance runners are much leaner due to the excessive amount of long distance runs they do on a weekly basis. Half marathoners also do a fair amount of speed work and weights, which ensures that their neuromuscular fitness is sufficient to allow them to take advantage of their aerobic fitness. Because of this the half marathoner would be much closer to a 400m runner in a 400 than the 400m runner would be to the half marathoner in a half marathon. When I say closer, I mean percentage wise because it would be unfair to compare them by time difference due to the distance discrepancy between the two events. The half marathon would allow for a much bigger time difference than the 400 due to the distance discrepancy. I hope this information helps you decide which athlete is the most fit!
i am 13 and i got 57 for 400m
Bolt has run 45.28s for 400m.
It Depends ..... If You Are An Track Runner And You Are An Boy You Should Make It In Atleast 50 Sec If You Are An Girl That Runs Track You Should Make It In Atleast 52 Sec -Marteas
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.
The average momentum of the runner in this case can be calculated by multiplying the mass of the runner by the average velocity. The average velocity of the runner is the total distance divided by the total time taken, which in this case is 400m/50s = 8 m/s. Therefore, the average momentum is 50 kg * 8 m/s = 400 kg.m/s.

The record time for the Boston Marathon is 2 hours, 7 minutes, and 14 seconds. Over 26.2 miles, that's an average of about a 4 minute, 48 second mile, or about 12 mph.
no not at all
