So 120/2 and x/4 p.s it can also be written 120/x = 2/4 depending on which way you like to solve proportions. Cross multiply 4· 120= 480 and 2·X= 2x Divide 480 by 2 and x= 240

120 miles - 2 hours
x miles - 4 hours
cross multiply:
[tex]2x=4 \times 120 \\ 2x=480 \\ x=\frac{480}{2} \\ x=240[/tex]

It will travel 240 miles.
