they time it in hundredths because often times in the 100 meter dash two people may have the same tenth time so the more precise you can get the timing the better

What unit of time is suitable for measuring the time of a 100- meter race?
One hundredths of a second.One hundredths of a second.One hundredths of a second.One hundredths of a second.
What unit would you use to measure time to run a race?
The answer depends on the distance. Marathons are measured in hours and minutes, sprint distances in hundredths of a second.
Why are times at a school event not usually measured to the nearest hundredth of a second?
Because most people are not interested in that degree of accuracy. Furthermore, human response times are slower than that so it would require expensive equipment to time events to hundredths of a second.
If speed is measured in meter per second and time is measured in seconds what is the Si unit for acceleration?
It is metres per second per second or metres per second squared.
When work is measured in joules and time is measured in seconds power is measured in what unit?
Watts. A watt is a joule per second.
What is the speed of a ball if it is dropped from 95 inches and hits the ground at 56 hundredths of a second?
rule is:average speed = distance/time taken=95inches/56 hundredths of a second=95/0.56=169.6428571 inch/second
Is time categorical or measurement?
Time is also measured; the unit in SI is the second (s).
What is jerk measured in?
Jerk is measured in (distance) per (unit of time) cubed; for example, feet/second cubed.
What is acceleration measured in?
Acceleration is measured in (distance) per (unit of time) squared; for example, feet/second squared in the SI (metric) system the official unit is metres/second/second or metres/(second squared)
What would be the most practical unit to use for expressing the time it takes to blink?
Hundredths of a second.
How do you calculate speed in miles per second?
The distance travelled, measured in miles divided by the time taken, measured in seconds.
What is the unit of measurement used to express the energy emitted per second?
Power. In SI, energy is measured in Joule, and power is measured to watts (= Joule per second).Power. In SI, energy is measured in Joule, and power is measured to watts (= Joule per second).Power. In SI, energy is measured in Joule, and power is measured to watts (= Joule per second).Power. In SI, energy is measured in Joule, and power is measured to watts (= Joule per second).
