Need some help with this question. I think I know how to do it but I don't know the speed of sound. Could someone let me know what it is?
A rifle is fired in a valley with parallel vertical walls. The echo from one wall is heard 6.0 s after the rifle was fired. The echo from the other wall is heard 6.0 s after the first echo. How wide is the valley?
