Question

A sound beam travels a total of 10 cm in 2 seconds. What is the speed of the sound?

A. 5 cm/s.
B. 10 cm/s.
C. 20 cm/s.
D. 2.5 cm/s.

Answer 1

The speed of the sound beam is 5 cm/s.

Step-by-step explanation:

The speed of a sound wave can be calculated by dividing the total distance traveled by the time taken. In this case, the sound beam travels 10 cm in 2 seconds, so the speed of the sound is 10 cm/2 s = 5 cm/s.
