What average cruising speed in kilometers per hour ($ ext{km/h}$) is used for calculating the jetliner flight time around UY Scuti?

Answer

Around 925 kilometers per hour

The mathematical exercise of determining the flight duration relies on a consistent speed measurement for the hypothetical traveler. The established speed for the modern commercial jetliner, used for this calculation, is cited as averaging around $925$ kilometers per hour ($ ext{km/h}$). This metric speed is preferred over the equivalent speed in miles per hour (about 575 mph) to maintain consistency when dividing by the circumference, which was calculated in kilometers. This specific speed parameter is vital for obtaining the final result of approximately 917 years.
