Answer:

The distance travel in its lifetime of earth is

$x=1.7595m$

Explanation:

Change respecto the pion

The speed of the pion:

Knowing the speed of the light is about

$v_l=3x10^{8}$

$v_p=3x10^{8}*0.23c=69x10^6$

Now to determinate the distance

$v=\frac{x}{t_p}$

$x=v*t=69x10^6m/s*2.55x10^{-8}s$

$x=1.7595m$
