(b) An aircraft leaves California on Monday at 14: 30 and arrives in Switzerland on Tuesday at 12: 00 local time.

So, the time in Switzerland when aircraft leaves California is 14:30+9=23:30pm(Monday) .

It arrives at Switzerland at 12: 00 on Tuesday.

So, duration will be: 30minutesofMonday+12hoursoftuesday=12:30means12hoursand30minutes

(ii) The distance from California to Switzerland is 9352 km and taken time is 12: 30 = 12.5 hours

So, Average speed = 935212.5=748.16kmh=748.16×10003600ms=

=207.82ms
