Answer:
root-mean-sqaure = 2.77 m/s
average = 2.72 m/s
The root-mean-square is always the largest because it takes account of the variance of the spread of the data. The increase is related to the fact that the data varies to sample.
Explanation:
The rootmean-square (R) is the square root of the squares of the valeus divided by the number of the datas.
![R = \sqrt{\frac{x1^2 + x2^2 +...+xn^2}{n} }](https://tex.z-dn.net/?f=R%20%3D%20%5Csqrt%7B%5Cfrac%7Bx1%5E2%20%2B%20x2%5E2%20%2B...%2Bxn%5E2%7D%7Bn%7D%20%7D)
![R = \sqrt{\frac{(2.0)^2 + (2.2)^2 + (2.6)^2 + (2.7)^2 ^(3.3)^2 + (3.5)^2}{6} }](https://tex.z-dn.net/?f=R%20%3D%20%5Csqrt%7B%5Cfrac%7B%282.0%29%5E2%20%2B%20%282.2%29%5E2%20%2B%20%282.6%29%5E2%20%2B%20%282.7%29%5E2%20%5E%283.3%29%5E2%20%2B%20%283.5%29%5E2%7D%7B6%7D%20%7D)
R = √(46.03)/6
R = 2.77 m/s
The average speed is the sum of the speeds divided by the number of datas:
![A = \frac{2.0 + 2.2 + 2.6 + 2.7 + 3.3 + 3.5}{6}](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7B2.0%20%2B%202.2%20%2B%202.6%20%2B%202.7%20%2B%203.3%20%2B%203.5%7D%7B6%7D)
A = 16.3/6
A = 2.72 m/s

Explanation:
The word "science" was obtained from the Latin word "Scire" which means "to know". Hence science is a systematic investigation into the nature of the universe.
Scientific investigations begin with asking questions about the universe. It is this curiosity to know about occurrences in the universe as well as how to solve problems in the universe that leads to fascinating scientific investigations and discoveries.
