- Homework Statement
- Two persons, A and B were interest to find out the speed of the sound in the air. They stand 40 m of a wall and 60 m from each other. The person B hears the sound that A said. And after 1/8 seconds he hears the echo created by the wall. Based on this measures, what is the value these two people obtained for the speed of sound?
Solution: 340 m/s
- Relevant Equations
- v = d/t
d² = 40² + 60² ---> I
60 = V.t ---> II
40 + d = V.(t + 1/8) ---> III
Thanks in the advance. :)
