The speed of sound is the measure of how far it travels in a certain amount of time. the speed of sound will differ depending on which of the following?

a) the frequency of sound.

b) where the sound originated from.

c) the pitch of sound.

d) the material the sound is traveling through.

Explanation:

The speed of sound depends on the elasticity and density of the medium through which it is traveling. In general, sound travels faster in liquids than in gases and faster in solids than in liquids. The greater the elasticity and the lower the density, the faster sound travels in a medium.

Option D is the correct answer.

Explanation:

The speed of sound refers to the distance travelled per unit time by a sound wave as it moves. At 68º F its speed in air is about 343 meters per second, or 767 miles per hour or a kilometer in 2.9 seconds. There are two big factors to be considered: first one is temperature and the material the sound is traveling through, so the last option is the right answer.
