    Did You Calculate the Speed of Sound Correctly?

    Thanks for helping out, Merlin 3189 and Tsny. I really appreciate it. Well observed. There's a mistake, the solution is 320 m/s. The grey arrows should have the end curved in both sides, so A is looking at B and B looking at A and A is looking at wall and wall is facing A. I'm sorry for the...

    d² = 40² + 60² ---> I 60 = V.t ---> II 40 + d = V.(t + 1/8) ---> III Thanks in the advance. :)
