It will vary from 60-100 beats/minute depending on your physical condtion and weight.

1 meter - 100 cm So it would be 0.14 m
About 16 seconds for a slim semi-fast girl
normal
He runs the 100 meters in 9.98
he ran 10.78 for 100 meters
98.63mph
2.5 seconds
A time of 15.1 seconds in the 100 meters for a 12 year old is a good time. It is not considered especially fast, but it is likely as fast or faster than average.
