A bus driver runs a round trip route between 3 cities. It takes 5 hrs for the 400 km trip to the first city. Reloading the bus takes 30 minutes. On the road again, it takes 3 hrs 15 min to get to the second city, which is 220 km away. After a 1 1/4 hr supper, he drives back to his home city which is 280 km away in 4 hrs. What average speed did he have for the day's drive?
