Brian drove 120 miles at speed of 60 miles per hour. He drove the same distance back home at average speed of 40 miles per hour. Brian adds these speeds and divides by 2 to come up with an average speed of 50 miles per hour. What is wrong with his reasoning? Find his average speed.
To find average speed, Brian should not divide the sum of the speeds by 2. He should find the total distance and divide this value by the total time of the trip. 240 miles / 5 hours = 48mi/h
