The PEP was a collider in which the two beams of e + and e collided

Question:

The PEP was a collider in which the two beams of e⁺ and e^– collided in the CM reference frame. Consider the beam energy E_cm= 29 GeV and the reaction e⁺ + e^- → τ⁺ + τ ^–. Find the average distance the τ will fly before decaying.
