It will depend on how fast you are going. At 60 kmph it would take you 106.6 hours.
6,400,000 m
360 ÷ 40 = 9 hours (Note: every hour you will have travelled 40 km.)
900
Suppose you go by speed 50 km p h then you need 10 hours to cover that distance. So if, in general, v km p h is the speed then the time taken to cover 500 km will be got by 500 / v in hours.

Answer: 6400 km = 3,976.775 mi.
You are traveling at 1,280 km per hour.
It is approx 7044 km.
