Use 80% *25 than you can get 20.
        
             
        
        
        
Given that <span>For
a certain model of car the distance 

 required to stop the vehicle if
it is traveling at 

 mi/h is given by the formula 
![d=v+\frac{v^2}{20}, where [tex]d](https://tex.z-dn.net/?f=d%3Dv%2B%5Cfrac%7Bv%5E2%7D%7B20%7D%2C%20where%20%5Btex%5Dd%20)
is measured in feet. 
If Kerry wants her stopping distance not to exceed 75
ft, then the range of speeds (in mi/h) can she travel is obtained as follows:

Therefore, the range of speed she can travel is
