Los Angeles International to Rapid City Regional LAX → RAP
936 nautical miles (1,077 statute miles) northeast on a straight line, true course 045°, about 033° magnetic at the departure end (variation 12E). At 120 knots that is 5 h 12 min at the quickest height in today's winds (39,000 ft, a 60-knot tailwind), arriving about 11:20 pm MDT (05:20 UTC), after sunset at the destination. Right now LAX is VFR, wind from the west-southwest (240°) at 9 knots; RAP is marginal VFR, wind from the northeast (050°) at 8 knots. For planning, not a briefing: the legal preflight briefing comes from Flight Service (1-800-WX-BRIEF) or the FAA's own tools. Airlines fly this pair: 1 flights in the DOT's last twelve reported months, the route's page.

The eastbound cruising heights for this course (VFR: odd thousands plus 500 ft; above 18,000 ft the forecast levels), with the wind averaged along the line from the 9 forecast points nearest it (ONT, WJF, LAS, BCE, SLC, RKS, LND, BFF, RAP). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 11th at 18:00 UTC; valid on the 12th at 00:00 UTC for use 20:00 to 03:00 UTC; temperatures above 24,000 ft are below zero. Heights are above sea level; a height is left out when the forecast has no wind for it over most of the line (the ground is higher). Ground speed is the airspeed less the headwind; the time en route is for the straight line and ignores climb, descent and routing around weather.
