Disclaimer: There are a plethora of ways to solve this problem, but I decided to utilize proportions to solve it, as I believe that it is the easiest method to solve these types of questions.
1. Set up your proportion
2. Set up a basic algebraic equation: 1x=700
In other words, what times 1 is 700?
Multiply 1*700, which is 700, and do the same for the bottom.
1.61*700= 1,127
3. The final answer is 1,127 kilometers. Please refer to the pictures attached for a more visual and thorough explanation. Cross mutiplying could also be used. Simply cross multiply in your proportion to get your answer.
