A hunter fires a gun at a point 408 m away from a cliff. If he hears an echo 2.4 s later, determine the speed of the sound wave
-
340 ms\(^{-1}\)
- 380 m s\(^{-1}\)
- 400 m s \(^{-1}\)
- 680 m s\(^{-1}\)
The correct answer is: A
Explanation
speed of the sound wave = \(\frac{distance * 2}{time}\)
= \(\frac{408 * 2}{2.4}\)
: speed of the sound wave = 340 ms\(^{-1}\)
