Light travels at a speed of 3x108meters / second in a vacuum (such as outer space).  This is technically the fastest known speed in the universe. When the speed of light travels in mediums other than in a vacuum, it technically travels a bit slower than that. Consequently, a light ray will...

Take inverse natural log for both sides of the equation.   elog(x+16) = e(log x + log 16)   Since log ab = log a + log b  , we can apply this to the right side of our equation...   elog(x+16) =  e(log 16x)   Since...

For the conditions stated, if one line segment (PX) is twice the length of the other (XQ), then point X must be 2/3 of the way towards Q because let s = the length of XQ and 2s = length of PX 2s / (2s +s) = 2s / 3s  = 2/3   Therefore, if we go 2/3...
