So, let's make 2 into 6/3, and then add it to 1/3. That gives us 7/3. Now, let's divide 45 by 7. We get 6.43. Let's multiply that by 3. 19.29. Let's round down to the nearest whole number, which is 19. This gives us the answer of 19 miles. 19.29 miles may work as well if you're looking for the answer rounded to the nearest tenth.
