The distance from the edge of the well to the water's surface = 11.25 m

Explanation:

Using equation of motion: s = ut +1/2 at^2

where s is distance, t is time = 1.5sec
u is initial velocity= 0 as it starts from rest,
and a is acceleration due to gravity ~~10 m/s^2 .

s= 0 xxt + 1/2 axxt^2

s= 1/2 xx 10 ms^-2xx (1.5)^2 sec^2

s = 11.25 m
