Correct Answer: Ratio
Determining a person’s reaction time would involve measurement on a
ratio scale that is expressed in milliseconds. It is a point where none of the quality being measured
exists and its scale has an absolute zero. In ratio scale, it allows comparisons
such as being twice as high or one-half as much. Additionally, in the case of a
person’s reaction time, it can be state that a response of 25 milliseconds is
twice as fast as a response time of 50 milliseconds.
The part of the plant cell that gives it the green color is an organelle called the chloroplast. Inside the chloroplast there are pigment molecules called chlorophyll, which is the substance that gives the plant the green color.
Answer:
30meter per second
Explanation:
Given that
Distance = 3000 meters
Time = 100seconds
Speed = distance /time
Substituting the values
Speed = 3000/100
Speed = 30meter per second
The average speed needed to cover the travelling will be 30meter per second.
