As it turned out, the tournament ended early. Alice, of course, had not arrived yet. John decided to begin walking home. He eventually met Alice enroute and she drove him the rest of the way home. They arrived home at 6 pm - 6 minutes earlier than they would have if he had just waited at the bowling alley.
Assuming that John and the car traveled at steady speeds, and that the car traveled 10 times faster than John walked:
What time would have they arrived at home if Alice had been waiting for him when the tournament ended?
