Aperson with his ear to the ground, sees a huge stone strikethe concrete pavement. a moment later two sounds are heard from theimpact: one travels n the air and the other in the concrete, andthey are 2.2 s apart. how far away did the impact occur?
*the speed of sound for air is 343 m/s, for concrete˜3000.
show how you set up the problem and how you got youranswer.

852.014 m

Explanation:

The speed of sound in air = 343 m/s =

The speed of sound in concrete = 3000 m/s =

The distance the sound traveled = s

Time between the sounds heard  = 2.2 seconds

Time = Distance / Speed

Time taken by sound travel through air

Time taken by sound travel through concrete

So,

The impact occurs 852.014 m away from the person.
