Answer:

#m=(Pt)/(gh)#

Explanation:

#P=(mgh)/t#

#P/1 = (mgh)/t#

Now cross multiply #t# with #P# and multiply #1# with #mgh#. Then, take #m# as common multiple and make a fraction form by dividing

#m = (Pt)/(gh)#

We assume that the symbols used in the equation

#P=(mgh)/t#
are #P# Power, as power is the rate of doing work.
#t# time
#mgh# potential energy due to gravity

As such #m=# mass of the object under consideration.
