On Friday night, 19 European partners and 7 Indonesians flew out to Papua with 50 pieces of luggage weighing a total of 1.1 ton, including 500 kg of diving equipment. Fortunately, the latter was not charged as extra and overweight luggage.

They travelled approximately 2850 kms stopping on the way at Makassar on the island of Sulawesi (formerly Celebes).

A little arithmetic quiz:

With an estimated take-off at 9 pm delayed by one hour, 2 hours of flight between Jakarta and Makassar, a 2h15 wait in Makassar, and a 2h15 flight between Makassa and Sorong: when exactly did they arrive in Sorong? Remember that there are two time zones between the island of Java (where Jakarta is situated) and Papua.

Tie-break:

Knowing that in this season (summer time), the jet lag between France and Papua is of 7 hours, at what “French time” did they arrive?
