Kinzhal Ballistic missile apogee

[Vanessa1402]

Is there anyway to convert ballistic missile apogee to the re-entry speed and range?.
How can Kinzhal reach such high speed and range with apogee of only 20 km?

Quasi-ballistic flight profile?

20 km is the altitude of Mig-31 before launching Kinzhal, not the apogee of Kinzhal
