Answer:
A.
Step-by-step explanation:
Since they are similar, hence taking proportionality,
CA/CB = d1/d2
Cross Multiplying
We get
CA × d2 = CB × d1
OR
d1×CB = d2 × CA

First, divide 648 by 9. 648/9=72. Now we know that Ashley covers 72 miles in an hour. In order to get the number of miles she covers in 7 hours we must multiply 72 by 7 which equals 504. So Ashley would drive 504 miles in 7 hours.
