I’m confused U.S.A./Rus say its takes thier nukes 15 minutes to reach each other at 24K MPH (just over Mach 30) it seems as if it would be 1 hour before the missiles reach unless they go 96,000 mph (15 minutes)????

Based on what launch sites?

May have something to do with sub-launched missiles or something to do with trajectories (no idea what i’m saying here).
