While filming an intense action sequence for the next james bond movie, a controlled explosion detonates 1.1 km away from the actors. if the speed of sound through solid rock is 3000 m/s on average, the actors will feel the explosion before they hear it. how much time will pass between when they feel the explosion and when they hear it?

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:

(Remember that the sound speed in the air is 340 m/s on average)

So, the time between the feeling and hearing is 3,23 - 0,37 = 2,86 secs
