A stone is dripped into the well 44 meter dip the spalash in heard in 3.12 s find speed of sound in air.

The speed of sound is 366.67 m/s.

Explanation:

height, h = 44 m

total time, T = 3.12 s

Let the time taken by the stone to hit the water is t.

use second equation of motion

Time taken by sound to g up

t'=T - t =  3.12- 3 = 0.12 s

The speed of sound is

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
