PLEASE HELP! *WILL MEDAL* Mr. and Mrs. Miller both get in their cars and begin to drive at the same time. Mr. Miller is 280 mi from their house and drives directly home at a constant rate of 40 mph. Mrs. Miller is at their house and drives away from the house at a constant rate of 30 mph. Let d represent distance from home, and let t represent time in hours. Which system models this situation? A. d = 280 + 40t d = 30t B. d = 280 − 30t d = 40t C. d = 280 − 40t d = 30t D. d = 280 − 40t d = 280 + 30t
