Question no 610295. Speed is no problem.The drawing either, but:

sorry, variation is zero so Magnetic North is True North in this case...

....what I do not understand is that you measure True Track only from the 360 radial. True Track is constantly changing from A to B, isn't it ???
At 00:20 UTC an aircraft is crossing the 310° radial at 40 NM of a VOR/DME station. At 00:35 UTC the radial is 040° and DME distance is 40 NM. Magnetic variation is zero. What is the aircraft’s track and ground speed?

PLS EXPLAIN
