You and your father leave from home to have dinner at your grandmother’s house. You are cycling while your father is driving his car. If your father’s average speed is 30 km per hour and your average speed is 12 km per hour, then it takes 1 hour less on the bicycle than 3 times as long as your father in the car. How long does it take each of you to make the trip?
