Oliver and Ryan are both driving along the same highway in two different cars to a stadium in a distant city. At noon, Oliver is 350 miles away from the stadium and Ryan is 365 miles away from the stadium. Oliver is driving along the highway at a speed of 60 miles per hour and Ryan is driving at speed of 65 miles per hour. Let O O represent Oliver's distance, in miles, away from the stadium t t hours after noon. Let R R represent Ryan's distance, in miles, away from the stadium t t hours after noon. Write an equation for each situation, in terms of t , t, and determine the interval of hours, t , t, for which Oliver is closer to the stadium than Ryan.
