Supersonic planes fly at speeds greater than the speed of sound. The speed of sound is the speed at which sound travels through a medium, such as air. It is about 767 miles per hour (1,235 kilometers per hour) at sea level. Supersonic planes can fly at speeds of up to Mach 2, which is twice the speed of sound. This means that they can travel from New York to London in about three hours.<\/p>\n<p>Option A is incorrect because supersonic planes fly at speeds greater than the speed of sound. Option B is incorrect because the speed of sound is the speed at which sound travels through a medium, such as air. Option D is incorrect because the speed of light is much faster than the speed of sound.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;less than the speed of sound&#8221;
