Given:
Light speed = 186,000 miles per second
Sound speed = 1,087 feet per second
Find how much faster does a light travels compared to sound.
Solution:
Since sound speed is in the unit feet, and light is in the unit miles, convert first miles to feet.
1 mile = 5280 feet
= (186,000)(5280)
=982,080,000 feet per second
Subtract the speed of sound from the speed of light in order to determine the difference in speed.
Difference in speed = x
x = Speed of light - speed of sound
x = 982,080,000 feet per second - 1,087 feet per second
x = 982,078,913 feet per second
