I'm still reading the challenge but I got stuck with the above.
B fires, and sound B begins its 30-second journey to C.
After 10 seconds -- i.e. with
20 seconds left (30 - 10 = 20) on sound B's journey to observer C -- A fires.
Sound A
consumes 1 second of the remaining 20 to travel to C. Therefore the correct equation is
20 - 1 = 19, not 20 + 1 = 21. By the time sound A reaches C, sound B has 19 seconds to go to get to C, not 21.
Observer C will perceive
a 19-second delay from shot A to shot B.
Please correct me if I am wrong.
