Several dump trucks, standing in line, are loaded in turn at point A (the loading time is the same for all trucks) and transport the load to point B, where they are immediately unloaded and return to A. The speeds of the trucks are the same; the speed of a loaded truck is 6/7 of the speed of an empty one. Driver Petrov was the first to leave point A. On his way back, he met driver Ivanov, who had left point A last, and arrived at A 6 minutes after the meeting. Petrov immediately began loading upon arrival, and after finishing, he headed to point B and met Ivanov a second time 40 minutes after the first meeting. From the place of the second meeting to point A, Ivanov drove for at least 16 minutes but no more than 19 minutes. Determine the loading time and the number of dump trucks being loaded.
