Answer:4800 km in 8 hours at a constant speed.
Explanation:
If you do 600(2)+300. You will get 1500 km which is at a constant speed in 2.5 hours. If you want to find the unit rate of the speed you will take 1,500 divided by 2.5 to get you 600. If your trying to find how many km you will travel in 8 hours at a constant rate, you should take 600(8) which should get you 4800 km.
