OLYMPIC SPEED SKATING TIMES HAVE GENERALLY BEEN DECREASING OVER TIME THE FORMULAS W=-0.17t+ 53 and M=-0.12t+46

Consider the equations:

y = -0.17x + 53

y = -0.12x + 46

=> -0.17x + 53 = -0.12x + 46

=> -0.05x = -7

=> x = 140

y = -0.17(140)+53 = -23.8+53 = 29.2

Hence afer about 29 years the Men\'s and Women\'s time will be equal
