Correct answer is... 3 m/s It is equal to 591 ft/min. It is lower then climb speed of other aircrafts with similar size. Average is about 8.3 m/s or 1629 ft/min.

To give an example, CAB Minicab with it's climb speed of 3 m/s that takes off from airfield of elevation 100 metres (300 feets) will reach flight level 100 (10,000 feets or 3 km above mean sea level) after about 17 minutes.
