Canadian Actor William Shatner travelled on the Blue Origin rocket in October \(2021\). He was in the rocket for \(10\) minutes and \(17\) seconds after liftoff, before landing back on the desert floor in Texas. The rocket rose to an altitude of \(105.9\) km.
If his flight was straight up and down, what was his mean speed, to the nearest kilometre per hour, over the course of the whole journey?
The length of the Trans-Canada Highway between the east and west coasts of Canada is \(7821\) km. If the rocket travels a distance of \(7821\) km at the mean speed found in part (a), approximately how long (in hours and minutes) would that trip take?
