There is no "physics explanation". You're given an information set that
could apply equally well to two different physical situations. You're
simply not given enough information to distinguish between them.

600=v * t (1)
1000= (v+50) (t+1) (2)

from (1) t= 600/v

--> 1000v=(v+50)(600+v) --> v^2 - 350v + 30000 = 0

Math books do explain these things.
