The distance from Centerville to a freight train is given by the expression \(-10t + 115\), and the distance from Centerville to a passenger train is given by the expression \(-20t + 150\).
The expressions above give the distance from Centerville to each of two trains \( t \) hours after 12:00 noon. At what time after 12:00 noon will the trains be equidistant from Centerville?
