Answer: 67.2 kilometers
Explanation: To convert 42 kilometers into miles, we start with our conversion factor for kilometers and miles which is shown below.
1.6 kilometers = 1 mile
Next, notice that we're going from a larger unit, <em>kilometers</em>, to a smaller unit, miles. When we go from a larger unit to a smaller unit, we multiply.
So we multiply 42 miles by the conversion factor, 1.6 toget 67.2.
So 42 miles is approximately equal to 67.2 kilometers.
