Sometimes, highway signs indicate distances to the upcoming exits in both miles and kilometres. One such distance is given as 17.0 miles. What is this distance in kilometres?
Solution
To convert miles to kilometres, you use the conversion factor:
1 mile ≈ 1.60934 kilometres
or a distance of 17.0 miles:
17.0 miles * 1.609344 km / mile = 27.358848 km
Rounding to a standard level of precision (such as one decimal place, which is common for highway signs), the distance is approximately 27.4 kilometres.
