4. ketisha is practicing for a marathon by running around a track that is 440 yards long. yesterday she ran around the track 20 times. how many miles did she run?

Solve the problem by making up an equation. a man could arrive on time for an appointment if he drove the car at 40 mph; however, since he left the house 15 minutes late, he drove the car at 50 mph and arrive 3 minutes early for the appointment. how far from his house was his appointment?
