Correct answer is... 1.9 m/s It is equal to 380 ft/min. It is lower then climb speed of other aircrafts with similar size. Average is about 3.7 m/s or 720 ft/min.
Climb speed is counted in km/h or mph units. It would not be handy for pilot to convert it from hours to lower values. So climb speed is often described as vertical distance per seconds or minutes. To give an example, British Aircraft Company Drone with it's climb speed of 1.9 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 26 minutes.
