Calculate the speed of sound in different media (air, water, steel, etc.). Adjust temperature for air and find travel time over a distance.
m/s
| Speed (m/s) | 343.4 m/s |
| Speed (ft/s) | 1126.7 ft/s |
| Speed (km/h) | 1236.3 km/h |
| Speed (mph) | 768.2 mph |
| Travel time over 1000 m | 2.9119 s |

Air: v = 331.3 + 0.606 × T(°C) m/s
Mach 1 ≈ 343 m/s at 20°C in air
Travel time = Distance / Speed
At 20°C (68°F), sound travels at approximately 343 m/s (1,125 ft/s or 1,235 km/h) in air.
Yes. In air, speed increases ~0.6 m/s per 1°C rise. The formula is v = 331.3 + 0.606 × T(°C) m/s.
Water — sound travels ~1,480 m/s in water, about 4.3× faster than in air at room temperature.
Sound travels approximately 5,100–5,900 m/s in steel, much faster than in air or water.
