The bus driver's manager wants to know the average speed at which the driver was actually driving the bus that day while he was on the road. DON'T include the rest stops.
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?
