Answer:
or ![3.6\ sec](https://tex.z-dn.net/?f=3.6%5C%20sec)
Step-by-step explanation:
we know that
To find out how much faster is Paloma than Savannah in the 100- meter dash, subtract the Paloma's time from the Savannah's time
so
![19.8-16\frac{1}{5}](https://tex.z-dn.net/?f=19.8-16%5Cfrac%7B1%7D%7B5%7D)
step 1
Convert mixed number to an improper fraction
![16\frac{1}{5}\ sec=\frac{16*5+1}{5}=\frac{81}{5}\ sec](https://tex.z-dn.net/?f=16%5Cfrac%7B1%7D%7B5%7D%5C%20sec%3D%5Cfrac%7B16%2A5%2B1%7D%7B5%7D%3D%5Cfrac%7B81%7D%7B5%7D%5C%20sec)
step 2
Convert decimal number in fraction number
![19.8\ sec=\frac{198}{10}\ sec](https://tex.z-dn.net/?f=19.8%5C%20sec%3D%5Cfrac%7B198%7D%7B10%7D%5C%20sec)
Simplify
![\frac{99}{5}\ sec](https://tex.z-dn.net/?f=%5Cfrac%7B99%7D%7B5%7D%5C%20sec)
step 3
Substitute the values
![19.8-16\frac{1}{5}=\frac{99}{5}-\frac{81}{5}=\frac{18}{5}\ sec](https://tex.z-dn.net/?f=19.8-16%5Cfrac%7B1%7D%7B5%7D%3D%5Cfrac%7B99%7D%7B5%7D-%5Cfrac%7B81%7D%7B5%7D%3D%5Cfrac%7B18%7D%7B5%7D%5C%20sec)
Convert to mixed number
![\frac{18}{5}\ sec=\frac{15}{5}+\frac{3}{5}=3\frac{3}{5}\ sec](https://tex.z-dn.net/?f=%5Cfrac%7B18%7D%7B5%7D%5C%20sec%3D%5Cfrac%7B15%7D%7B5%7D%2B%5Cfrac%7B3%7D%7B5%7D%3D3%5Cfrac%7B3%7D%7B5%7D%5C%20sec)
Convert to decimal number
![\frac{18}{5}\ sec=3.6\ sec](https://tex.z-dn.net/?f=%5Cfrac%7B18%7D%7B5%7D%5C%20sec%3D3.6%5C%20sec)
