11.875 m/s
speed = 525/75 = 7 meters per second distance = speed × time distance = 7 × 60 distance = 420 meters
1 meter per second
speed = distance/time = 330 m / 40 s = 8.25 m/s
Speed (m/s) = Distance (m) / Time (s)Speed = 400 / 50Average Speed = 8 metres per second
The top running speed for a 12 year old boy is about 1 mile in 8 minutes. Anything at around 8 minutes and 40 seconds per mile is considered great.
that's freaky fast
I'd say about 27 seconds
that's great a 14 year old should be running it under 12.50 seconds but that's crzy good, i run it in 12.37 seconds
I do not know. But when i was twelve, I ran a 100meter dash in about 12, 13 seconds. Is that good?
The answer is 15s by the way.
My son is 9.5 years old and does 21.5 seconds, he is pretty good at his class
Running boy has kinetic energy. it is because of motion.
