Forget the numbers and think about how speed works for a second. If a plane flies at 600km/h, this means that it will fly exactly 600 km in 1 hour. So, how long would it take to fly 2400 km??
2400/600 = 4hours.
Do this for all three and add up the hours.
Total time: 12 hours
Average speed is the total distance / total time.

Average speed: 508.33333333 km/h
