You can put this solution on YOUR website! T(A)=3(A-20)^2 divided by 50+10
formula describes the average running time, T,l in seconds, for a person who is A years old to run the 100-yard dash. How long soes it tak,e a 30-year old runner to run the 110-yard dash?
------------------
T(30)= [[3(30-20)^2]/50] + 10
T(30)= [[3(10)^2]/50]+10
T(30)= [300/50]+10
T(30)= 6+10= 16 seconds
