Total time= 2.2 sec
Speed in air = 332 m/s
Total Distance = Speed x Time
= 332 x 2.2
= 730.4 m

Given,
Total time taken by sound=2.2 s
Speed of sound in air=332 m/s
Total distance travelled by sound=Speed x time=332 x 2.2=730.4 m
Now, the distance of tower from the person=Total distance travelled/ 2
=730.4/2
=365.2 m
