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 = ${\displaystyle \frac{1}{0.621}}$ 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.
${\displaystyle \frac{1}{0.621}}$ km = ${\displaystyle \frac{0.621}{0.621}}$ miles
$\Rightarrow {\displaystyle \frac{1}{0.621}}=1$ 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
