The height=500m
h=ut+0.5gt²
we initial velocity is zero
500=0.5 * 10 * t²
t=10 seconds
speed of the sound is 340 m/s
so time taken to travel 500m upwards is 500/340=1.47 sec
TIME TAKEN IS 10+1.47=11.47 sec
Hope it helps...

Answer:
Given,
Distance travelled by sound = height of water
- h = 500 m, g = 10
• Speed of sound = 340 m/s
Time taken by sound :
To find time taken by stone to reach down
- u = 0, g = 10 m second -square, h = 500 m
In 11.4 s the splash heard by a person on the top of the tower from the time of dropping the stone.
