We assume that the question is to find when men and women times reach equality. We substitute 't' with 'x' and set 'y' as the variable for when women and men times, in years, are equal, giving this system:
y=-0.20x+55
y=-0.16x+50

x=125
y=30
So this indicates that after 30 years the men and women times would be equal.
