Here is a video of a 777-300 retracting it's gear after departure. The whole sequence takes about 12 seconds. One of the LAST visible things happening is nose gear closure, at about 12 seconds.

There was an pilot/eyewitness who reported that EK521 was at 40-50 feet, at the threshold, with the gear down. Apparently this was communicated in a pilot whatsapp group.
So if your approach speed is, say, 150 kts and decaying, at the threshold at 40 ft. That gives a nice educated guesstimate for the beginning of the event sequence.
From the threshold at 40ft, a go-around is initiated. The gear lever is raised 2 seconds later. The a/c settles on the runway 12 seconds after that, at a badly decayed speed coming from 150kts. Is 120 kts a good guesstimate?
That is 135kts as an average speed between the threshold and touchdown after 14 seconds.
135kts is 250 km per hour. That is 69.44 meters per second. That means that the a/c touched down at about 1000 meters beyond the moment that the gear lever was raised.
They ended up near M13. Facing west (towards Mecca)
