To convert miles to kilometers, we use the conversion factor that [tex]\( 1 \text{ mile} \approx 1.6 \text{ kilometers} \)[/tex].
1. Identify the given number of miles:
We are given 45 miles.
2. Use the conversion factor:
To find out how many kilometers 45 miles is, we multiply the number of miles by the conversion factor.
[tex]\[
45 \text{ miles} \times 1.6 \text{ kilometers/mile}
\][/tex]
3. Perform the multiplication:
[tex]\[
45 \times 1.6 = 72 \text{ kilometers}
\][/tex]
4. Round the result to the nearest tenth if necessary:
In this case, 72 is already a whole number, so rounding to the nearest tenth gives us 72.0 kilometers.
Therefore, 45 miles is equivalent to 72.0 kilometers when rounded to the nearest tenth.
