2. the speed of sound is how fast the sound wave or the vibration travels through the object, medium, or matter. Depending on whether it is a solid, liquid, or gas, the sound will travel at different speeds. Sound will travel faster in water than in air, but much faster in steel.

4. Depending on whether it is a solid, liquid, or gas, the sound will travel at different speeds. Sound will travel faster in water than in air, but much faster in steel. The amount of moisture in the air will also affect the speed of sound. In dry air, sound will travel 768 miles per hour, but faster in water. At 768 mph, sound will travel one mile in 5 seconds through dry air, but four times faster in water, and 13 times faster through steel.
