Answer:
The time that will pass between the feeling and hearing the explosion is 2,86 secs
Explanation:
First, let's calculate the time that the wave takes to travel until the actors feel the explosion:
Now, the time that pass while the actors hear the sound is:
<em>(Remember that the sound speed in the air is 340 m/s on average)</em>
So, the time between the feeling and hearing is 3,23 - 0,37 = 2,86 secs
