Answer:

Solutions:

speed of sound = 330m/s

time = 15 sec

so, we know that

distance = speed ×time

distance = (15 ×330) m

distance = 4950 m

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.

Explanation:

Step 1: Scientists claim to have found the sound's fastest conceivable speed. Researchers discovered that solid atomic hydrogen could carry sound waves at a speed of 36 km/s. That is almost twice as fast as they can go through diamond, which is the world's hardest substance.

Given:

Speed of sound                           = 330 m/s

Time you hear the explosion     = 15 seconds

Step 2: Distance from explosion             = ? unknown

With some fluctuation for temperature, humidity, and altitude, the speed of sound is around 1,135 feet per second (fps), for context. Many pistol rounds have a faster than sound velocity. Every rifle load does. High-velocity rifle rounds may travel at speeds of up to 4,000 fps.

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.
