The distance to our nearest neighboring Star, is 4.4 light years. If there are 9.460x10^12 km in 1 light year, how far is this in miles?
So this is how I solved:
9.460x10^12 km x 1mi/1.61km x5.878x10^12 miles/1 light year x4.4 light years
My answer is 1.51x10^26 which i know is incorrect. How do i solve this?/
