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#
