Two space debris particles are moving in opposite directions

Two space debris particles are moving in opposite directions along the same elliptic orbit with focus F at the center of the earth. At time t = 0 particle m₁ is at perigee P and moving counter-clockwise, whereas particle m₂ collide at point Q after a time t₁. The semi-major axis (a) and the eccentricity (e) are known.

1.2) Determine the time t₁ from the perigee passage of m₁ (point P) to the collision point Q.
