An observer stands 43.0 m behind a marksmen practicing at a rifle range. The marksman fires the rifle horizontally which gives the speed of the bullet to be 939 m/s. How far does each bullet travel before the observer hears the report of the rifle? Assume that the bullet encounter no obstacles during this interval, and ignore both air resistance and vertical component of the bullet's motion. The speed of sound in air is 343 m/s.
