A person standing at a distance x in front of a cliff fires a gun .
Person B standing behind the person A at distance y from the cliff hears two sounds of the fired shot after 2s and 3s respectively .
Find x & y
[Speed of sound 320 ms^ -1 ]
______________________________
Formula used :-
s = d / t
___________________________
Got 2 Equation :
y-x = 640 --------> 1
y+x = 460 --------> 2
Now adding 1 and 2
=> 2y = 1600
=> y = 300 m
x = 160 m
