Two cars are traveling in the same direction. the first car is going 40 mi/h and the second car is going 55 mi/h. the first car left 3 hours before the second car. which equation could you solve to find how many hours it will take for the second car to catch up to the first car? a 40t+ 3 = 55t b 40t + 120 = 55t c 55t + 165 = 40t d 55t+ 3 = 40t
