The function d(x)=1375-110 represents the distance a high speed train is from its destination after x hours. How long does the train travel before reaching its destination
d(x)=1375-110x when it reaches 0 it has reached destination 0=1375-110x add 110x to both sides 110x=1375 divide both sides by 110 x=12.5 answer is 12.5 hour
