Answer:
Edgar has 36 minutes (11:00 pm - 10:24 pm = 36 minutes) to drive Addison home before the curfew.
To calculate the required speed, we need to use the formula:
Speed = Distance / Time
where distance is the distance to Addison's home, and time is the remaining time until curfew, converted to hours.
Time = 36 minutes / 60 minutes per hour = 0.6 hours
Speed = Distance / Time = 28.1 miles / 0.6 hours ≈ 46.83 miles per hour
Therefore, Edgar must average a speed of approximately 46.83 miles per hour to get Addison home on time.
