A bus spent a total of 8 hours traveling for a 600-mile trip. It took 5 hours to travel the first 420 miles. What was the average speed for the remainder of the trip?

Answer 1

Since it took 5 hours for traveling 420 miles, the remainder of miles is 180 (600-420) and the remaining hours are 3. Three divided into 180 equals 60 or 60 miles/hour.
