Question

If a kilometer is equal to $.612$ miles, how many kilometers is one mile equal to?

Answer 1

Hint: For answering this question we have been asked to find out how many kilometers is one mile equal to when a kilometer is equal to $.612$ miles. For doing that we will use the basic concepts of proportions and ratios which says that if $x$ in one unit is equal to $y$ in other units then 1 in the first units is equal to $\dfrac{y}{x}$ in other units.

Complete step by step solution:
Now considering from the question we have been asked to find out how many kilometers is one mile equal to when a kilometer is equal to $.612$ miles.
From the basic concepts of proportions and ratios we are aware of the statement which says that if $x$ in one unit is equal to $y$ in other units then 1 in the first units is equal to $\dfrac{y}{x}$ in other units.
Now we can say that if a kilometer corresponds to $.612$ miles then a mile corresponds to $\dfrac{1}{0.612}$ kilometers.
Therefore we can conclude that a mile is equal to $1.633$ kilometers.

Note: This is a very simple question from the concepts of proportions and unit conversions. This question can be answered in a short span of time and very few mistakes are possible in this question. Similarly we can convert any quantity from one unit to another. For example the value of one meter is equal to $100$ centimeters then the value of one centimeter is equal to $0.01$ meters.
