Divide the distance over the total time to find the distance Julia rides in one hour:
[tex]\frac{14\text{ miles}}{2\text{ hours}}=7\text{ miles per hour}[/tex]
Do the same for each option to find whether or not they represent the same speed:
A)
[tex]\frac{35\text{ miles}}{6\text{ hours}}=5.83\text{ miles per hour}[/tex]
B)
[tex]\frac{7\text{ miles}}{1\text{ hour}}=7\text{ miles per hour}[/tex]
C)
[tex]\frac{28\text{ miles}}{4\text{ hours}}=7\text{ miles per hour}[/tex]
D)
[tex]\frac{42\text{ miles}}{7\text{ hours}}=6\text{ miles per hour}[/tex]
Therefore, only options B and C represent the same ratio.
