$4500 \text{ km}\approx 2796.17\text{ mi}$

Work Step by Step

If we want to convert from kilometers to miles, we have to consider the following conversion rate: $ 1.609344\text{ km}\approx 1\text{ mi}$ We divide both sides by $1.609344$: $ 1\text{ km}\approx \frac{1}{1.609344}\text{ mi}$ We multiply both sides by 4500 in order to get the answer to the question: $4500 \text{ km} \approx \frac{4500}{1.609344}\text{ mi}\approx 2796.1704\text{ mi}$ After rounding to two decimal places: $4500 \text{ km}\approx 2796.17\text{ mi}$
