Question 1065626
R*T=W  for rate, time, amount of work.  The description does not specifically give the unit of work or the amount of snow.


If x is rate for 1 woman and y is rate for 1 man, then for the given described equal amount of work, "1 work" or "1 job",
{{{system((5y+4x)*6=1,(4y+6x)*5=1)}}}


{{{system(24x+30y=1,30x+20y=1)}}}
Multiply the first of these by 2, and the second of these by 3, to eliminate y and find x, first.


{{{system(48x+60y=2,90x+60y=3)}}}
-
{{{(90x+60y)-(48x+60y)=3-2}}}
{{{42x=1}}}

{{{highlight_green(x=1/42)}}}------in whatever units of work per day.


{{{30(1/42)+20y=1}}}

{{{20y=1-30/42}}}

{{{20y=1-5/7}}}

{{{20y=2/7}}}

{{{y=2/(140)}}}

{{{highlight_green(y=1/70)}}}------the rate for one man.


{{{system(1/42>1/70,x>y)}}}
The women are the better workers.
