Explanation:
A second of light is the distance that light travels in a second. It has a value of 299792458 kilometers or if we do the unit conversion, 186,000 miles. A mile is 1.609 kilometers
Let's make a rule of three:
1 light s travels a distance of 186000 miles
0.062500 light s would travel a distance of (0.062500 . 186000) = 11625 miles
Potassium -40half life = 1.28 ×10∧9.
