Answer 3

7 hours -------> 385 miles
1 hour --------> 385/7 miles
5 hours -------> (385/7)*5 miles

Answer 4

If you have learned proportions, you can also do this problem with a proportion.

385 miles is to 7 hours as x miles is to 5 hours

\(\dfrac{385}{7} = \dfrac{x}{5} \)

Now cross multiply and solve for x.
