Wendall and Sarah are taking road trips. Wendall travels for 20x miles per hour for x hours. Sarah travels for 5 more hours than Wendall at a speed that is 10 miles per hour less than Wendall. Which of the following functions will give the total number of miles that Sarah traveled on her road trip?
t(x) = 20x^2 + 90x - 50
t(x) = 10x^2 + 5x
t(x) = 20x^2 - 195x - 50
t(x) = 10x^2 - 50
