Answer:
2.48x10¹³ miles is the distance from the earth to Proxima Centauri
Explanation:
Light years is an unit of distance used in Astronomy. That is because 1 light year = 9.461x10¹²km; a real big distance used in the science that study the universe.
In km, 4.22 light years are:
4.22 light years * (9.461x10¹²km / 1 light year) = 3.9925x10¹³km
As 1 mile = 1.60934km, this distance in miles is:
3.9925x10¹³km * (1 mile / 1.60934km) =
2.48x10¹³ miles is the distance from the earth to Proxima Centauri
