A boat travels at a rate of 14 kilometers per hour from its port. A second boat is 38 kilometers behind the first boat when it starts traveling in the same direction at a rate of 18 kilometers per hour to the same port. Let d represent the distance the boats are from the port in kilometers and t represent the amount of time in hours. The system of equationsd = 14t + 38d = 18tcan be used to represent this situation. How many hours will it take for the second boat to catch up to the first boat? How far will the boats be from their port? Use the substitution method to solve this real-world application.
