Answer

$93\text{ km}\approx 57.79 \text{ mi}$

Work Step by Step

If want to convert from kilometers to miles, we have to consider the following conversion rate: $1.6093 \text{ km}\approx 1 \text{ mi}$ By dividing both sides by $1.6093$, we get: $1\text{ km}\approx \frac{1}{0.6093} \text{ mi}$ We mulitply both sides by 93 in order to get the answer to the question: $93\text{ km}\approx \frac{93}{1.6093} \text{ mi}\approx 57.789\text{ mi}$ By rounding it to two decimal places: $93\text{ km}\approx 57.79 \text{ mi}$
