a gun is fired at a distance of 24.3km away from man. he hears the sound after 27 second. find the speed of sound at which it travels.
16.42km/hr
speed is distance /time
24.3km/27s = 0.9km/s
To find the speed of sound, we need to use the formula:
Speed = Distance / Time
In this case, the distance is the distance between the gun and the man, which is 24.3 km. The time is the time it takes for the sound to reach the man, which is 27 seconds.
Substituting the values into the formula:
Speed = 24.3 km / 27 s
To calculate the speed, we need to convert the units to make them consistent. We can convert kilometers (km) to meters (m) by multiplying by 1000:
Speed = 24.3 km * 1000 m/km / 27 s
Simplifying:
Speed = 24,300 m / 27 s
Now, we can calculate the speed:
Speed = 900 m/s
Therefore, the speed of sound in this particular situation is 900 meters per second.
