Men's winning time to get equal to women's winning time means:
W(t)= M(t)
-0.176 t + 43.48 = -0.145 t + 39.83
43.48 - 39.83 = t (0.176 - 0.145)
0.031 t = 3.65
t = 3.65 / 0.031 = 117.74;
So, 1970 + 117.74 = 2087.74 ~= 2088;
Thus, men's winning time will become equal to women's winning time in the year 2088
