Explanation / Answer

we need to see the time difference in which they should reachif they occur simultaneously time difference =1200/c - 900/c = 300/c =10-3 ms so the events did not occur simulataneously the second event occured (2-0.001) ms after event 1 the second friend saw the events at the sane time distancecovered by light in (2-0.001) ms = 600000 m- 300 m so the second friend should stand such that the distance fromtree1 is (599700m) more than from tree 2
i believe the time should be in microsecond rather than ms asthese are not typical figures in that case also the approach should be the same just the calculation of second part will be easier
