first step divide
[tex]1200 \div 3[/tex]
because you got to find how far it traveled in one hour so it would be
[tex]400[/tex]
because 1200÷3=400
Second step you will do 400 times 2 because you got to find how far it traveled in 2 hours so it would be 800 because
[tex]400 \times 2 = 800[/tex]
so your final amswer is 800
