Ed and Flora drive at constant speeds toward each other on a highway. Ed drives at a constant speed of 31 km per hour. At a certain time they pass by each other, and then keep driving away from each other, maintaining their constant speeds. If Ed is 120 km away from Flora at 6 am, and also 120 km away from Flora at 11 am, then how fast is Flora driving (in kilometers per hour)?
