Group C: Harder, Faster, Stronger (thats what she said) (ha.)

100m Breaststroke Men

y=ax+b

y=(-0.17)x+405.1










100m Breaststroke Women

y=ax+b

y=(-0.22)x+505.7



y is the time in seconds
x is the years
a is the slope (-0.22 per year)
b is the y-intercept


The men's breaststroke times typically seem to be faster than the women's. We can predict that the times will keep getting faster and faster because as the years went on, the times got faster. An amazing time would be 30 seconds and we can expect this to happen in the year 2162 for the women, and in the year 2206 for the men.
