A 29-year-old engineer who specializes in soundproofing. about 0.29 second How long will it take to get to Mars in a spaceship? Here's a head turner: The speed of sound in a metal is 1000 m s-1. This was the best tool ive ever used that was on point from speed to distance and time Calculator. Using the observe() method, which does this, there is a difference of 0.02 seconds. The speed of sound through each medium is different and depends on the density and stiffness of the material. The speed of sound through water is about 1500 m/s, and it travels faster in salt water than fresh water. Each tool is carefully developed and rigorously tested, and our content is well-sourced, but despite our best effort it is possible they contain errors. Example: If a truck travelled at an average speed of 80 km per hour for 4 hours, how many miles did it cover in that time? But apparently it 2 mins. In an exceptionally stiff material such as diamond, sound travels at 12,000 m/s; which is around the maximum speed that sound will travel under normal conditions. SKYWARN Spotter Training How might form and function of a structure influence Aviation Weather, Climate The question then becomes, how long does it take light traveling at 11,802,827,520 inches per second to travel 1"? Outlooks Read More >, Current Hazards average speed = distance travelled time taken = 3.4 0.01 = 340 m/s For example, if you have distance in miles and speed in km/h, you will need to convert speed to mph or distance to kilometers. . The speed of sound depends on several variables, but the only independent variable we need to calculate the speed of sound is the temperature of the air. Thus, youll get that the lightning struck around 217 feet away. Please Contact Us. The wavelength formula of sound is the same as used for other waves: where is the wavelength of the sound wave, vvv its speed (in this case, speed of sound), and f its frequency. If a total distance of 2 miles is driven, with the first mile being driven at a speed of 15mph, and the second mile driven at a speed of 45 mph: What is the average speed of the full 2 mile trip?
