The average lifetime of a muon is 2.2 microsec. What is the average distance the muon would travel in free space before decaying according to a stationary observer watching the muon travel with a speed of (.60c).(adsbygoogle = window.adsbygoogle || []).push({});

I know how to find the proper time.

2.2/Sqrt[1-(.6c/c)^2] = 2.2/Sqrt[1-.6^2] = 2.2*1.25 =2.75 microsec

thank you in advance for any help.
