Effectiveness in pediatric patients below the age of 3 years has not been established. The starting dose is 300 mg three times a day. The effective dose of NEURONTIN is 300 mg to 600 mg three times a day. Dosages up to 2400 mg/day have been well tolerated in long-term clinical studies.n adults with postherpetic neuralgia, NEURONTIN therapy may be initiated on Day 1 as a single 300 mg dose, on Day 2 as 600 mg/day (300 mg two times a day), and on Day 3 as 900 mg/day (300 mg three times a day).
Quick Answer. The average cruising flight speed for commercial jets is around 540 mph. This is based on the most popular commercial jets in operation, the Boeing 747 family.
As indicated in the question, the speed of sound at 35,000 ft is 663 mph (1,067 km/h) according to the standard atmosphere model. Even if the plane's ground speed is over 700 mph, however, its airspeed will still be only 560 mph. As a result, the aircraft's Mach number turns out to be about 0.84, or 84% of the speed of sound. In other words, the Boeing 777 never flew faster than the speed of sound during your flight.
