Problem A bullet is fired at a target 1,342 m away. At what point along its path would the sound of the impact of the bullet be heard 1/4 second before the report of the gun, assuming that sound travels at the rate of 335 m/sec and the bullet is 503 m/sec.

Answer Key

Solution

$\dfrac{1342 - x}{335} - \left( \dfrac{1342}{503} + \dfrac{x}{335} \right) = \dfrac{1}{4}$

$x = 182.24 ~ \text{m}$ answer
