Question

a person hears an echo from the top of a tower, 2.2 seconds after the sound is produced. howv far away is the tower from the person speed of the sound in air is 332m/sec.

Answer 1

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

Answer 2

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
