It takes $~0.173~s~$ for the sound to reach the spectator's ears.
We can find the speed of sound at a temperature of $27.0^{\circ}C$: $v = (331+0.60~T)~m/s$ $v = [331+(0.60)~(27.0^{\circ}C)]~m/s$ $v = 347.2~m/s$ We can find the time it takes the sound to reach the spectator's ears: $t = \frac{d}{v}$ $t = \frac{60.0~m}{347.2~m/s}$ $t = 0.173~s$ It takes $~0.173~s~$ for the sound to reach the spectator's ears.
