Answer:

0.11 seconds

Step-by-step explanation:
= Time taken by the pebble to hit the water
= Time taken by the sound to travel to the observer
= Time taken by the observer to listen to the splash after stone is thrown = 3 s

a = g = Acceleration due to gravity = 
= Speed of sound = 340 m/s
The distance traveled by the pebble

Distance traveled by the sound

The distance traveled by the sound and the pebble is equal

Since
the value of
cannot be greater than 3.
So, time taken by the sound to reach the observer is 0.11 seconds.
Time taken by the pebble to hit the water is 
Depth of the well is
