Ashley drove 754 miles in 13 hours. at the same rate, how long would it take her to drive 522 miles?

A proportion will be used to solve this problem:

754 / 13 = 522 / x, where x is the unknown amount of hours.

To solve this proportion, we can cross multiply:

6786 = 754x.

Finally, divide both sides by 754:

9 = x.

At the same rate, it will take Ashley 9 hours to drive 522 miles.

If two angles are known to be the same, the triangles are similar! If this is true, then by default the third angle will be the same. So, triangles that have two of the same angles MUST be similar!
