![]() Table showing various speed of sound measurements converted to miles per hour. ![]() Speed of Sound to Mile per Hour Conversion Table The velocity in miles per hour is equal to the distance in miles divided by time in hours. Miles per hour can be expressed using the formula: For example, 1 mile per hour can be written as 1 mph, 1 mi/h, or 1 MPH. Miles per hour can be abbreviated as mph, and are also sometimes abbreviated as mi/h or MPH. The mile per hour is a US customary and imperial unit of speed. Next time you see lightning count the number of seconds before the thunder arrives, then divide this number by 5 to find out how far away the lightning is.Miles per hour are a measurement of speed expressing the distance traveled in miles in one hour. If you prefer to think in terms of miles, it takes sound nearly 5 seconds to travel 1 mile. If lightning occurs a kilometer away, the light arrives almost immediately (1/300,000 of a second) but it takes sound nearly 3 seconds to arrive. This is why we see it so much sooner than we hear the thunder. The flash of light from lightning travels at about 300,000 kilometers per second or 186,000 miles per second. Why do we see lightning before the thunder? speed of sound, speed at which sound waves propagate through different materials. ![]() In a small plane called the X-1, he was the first person to fly faster than the speed of sound and the listeners on the ground were the first to hear the loud shock wave of a sonic boom. On October 14, 1947, Chuck Yeager did just that. When a plane does go faster than speed of sound, it is said to break the sound barrier and a sonic boom is produced. That is the same as a car traveling about 780 miles per hour! Even most jet airplanes do not travel that fast. The speed of sound through warm air at sea level has been measured at 346 meters per second or 0.346 km per second. The longer it takes to hear the thunder, the farther the distance its sound had to travel and the farther away the storm is. Based on how much longer it takes to hear thunder tells us how far away the storm is. Choose the right category from the selection list, in this case Velocity. We see the lightning almost instantaneously, but it takes longer to hear the thunder. Convert Speed of sound to Miles per second (Mach to mps). We can also watch the speed of sound of a repeating simple harmonic wave. In non-humid air at 20 degrees Celsius, the speed of sound is about 343 meters per second or 767 miles per hour. The speed of sound is also equal to approximately 1,236 kilometers per hour ( km/h ), or 1,126 feet per second ( ft/s ), or 768 miles per hour ( mph ). ![]() Lightning and thunder both happen at the same time. We can find the speed of sound by looking at the speed of this compressed region as it travels through the medium. The same thing is at work during a thunderstorm. This is because the speed of sound is slower than the speed of light, which we are used to seeing. ![]() Or, you saw the drummer strike the drum, but it took an extra moment before you heard it. You saw the batter hit the ball, but did not hear the crack of the impact until a few seconds later. This speed of propagation of sound waves is very. If you have ever been to a baseball game or sat far away from the stage during a concert, you may have noticed something odd. The speed of sound is often expressed in meters per second but can also be converted to kilometers per hour. ![]()
