Question 222

A construction worker strikes a steel beam with a hammer. An observer stands at a distance of 1020 m from the worker.

The observer hears the sound of the blow 3.0 s after seeing the hammer hit the beam.

Using this information, what is the speed of sound in air?

A

170 m s−1170\text{ m s}^{-1}170 m s−1

B

340 m s−1340\text{ m s}^{-1}340 m s−1

C

510 m s−1510\text{ m s}^{-1}510 m s−1

D

1020 m s−11020\text{ m s}^{-1}1020 m s−1
