Question

If a kilometer is equal to .621 miles, how many kilometers is one mile equal to?

Answer 1

Hint: Use the conversion method to solve this question.
1 kilometer = 0.621 miles
If you want to find 1 mile in kilometer, divide 0.621 to 1.
That is 1 miles = $\dfrac{1}{{0.621}}$ kilometer

Complete step-by-step solution:
Given that, one kilometer is equal to 0.621 miles.
1 km = 0.621 miles
Divide both the sides by 0.621 in order to get 1 mile.
$\dfrac{1}{{0.621}}$ km = $\dfrac{{0.621}}{{0.621}}$ miles
$ \Rightarrow \dfrac{1}{{0.621}} = 1$ miles
1 miles = 1.610305 km
Consider up to 3 decimal places, 1 miles = 1.610 km.

1.610 kilometers is one mile.

Note: Find the list of some conversion students must remember,
1 kilometer (km) = 1000 meters (m)
1 meter (m) = 100 centimeter (cm)
1 centimeter (cm) = \[{10^{ - 2}}\] m
1 millimeter (mm) = \[{10^{ - 3}}\] m
1 micron (μ) = \[{10^{ - 6}}\]m
1 millimicron (mμ) = \[{10^{ - 9}}\]m
1 inch (in.) = 2.54 cm
1 foot (ft) = 30.48 cm
1 mile (mi) = 1.609 km
