I am posting here again after a long time. I have this distance measuring problem that I have been trying to solve. Please help me out here. TIA.
***A bullet covers distance of 1540 feet per second. Given the measurement, a person fired a shot and heard the sound of hitting the destination point after 3 seconds of firing. Speed of sound is 1100 feet per second.
What is the distance of destination point here?***
Waiting for your kind replies.

Let $d$ denote such distance. Then the total time for the bullet to reach the destination and for the person to hear the sound of hitting is simply $$\frac{d}{1540}+\frac{d}{1100}.$$ By condition, this should equal $3$. The answer will follow after your solving the equation about $d$: $$\frac{d}{1540}+\frac{d}{1100}=3.$$
