Sound travels at 14 speed of 330 meters per second. You hear a firecracker 15 seconds after it explode. How far is the explosion from where you are?

(can someone help me in this question?)

 

Good day...

Answer:

Considering that sound travels at a speed of 330 m/s, then the distance between you and the explosion of firecracker is 4,950 meters.

Given:

Speed of sound                           = 330 m/s

Time you hear the explosion     = 15 seconds

Distance from explosion             = ? unknown

Solution:

Speed of sound = distance / time

            330 m/s = distance / 15 s

           distance  =  330 m/s × 15 s    (cancel the unit second)

            distance  =  4,950 meters

The distance between you and the explosion of firecracker is 4,950 meters

Hope it helps.....
