x = 100m time from 30m to 250m

x = 400m time from 300m to 600m

y = total time in seconds

Approximate Formulas:

30m

y=-2.22+0.625x-0.005x^2

40m

y=-3.124+0.911x-0.016x^2

50m

y=-4.137+1.21x-0.027x^2

60m

y=-5.099+1.5x-0.038x^2

70m

y=-3.969+1.399x-0.029x^2

80m

y=-2.453+1.235x-0.018x^2

90m

y=-1.144+1.104x-0.009x^2

120m

y=2.453+0.765x+0.018x^2

150m

y=-2.096+1.774x-0.009x^2

200m

y=-6.056+2.994x-0.039x^2

250m

y=-14.781+4.955x-0.096x^2

Here’s a simple tutorial of how to use the graphs.

Ok so just to prove to you how fastidious i was in making these graphs here is a screenshot of the amount of work i put into just one of the equations using the quadratic regression calculator @

If you are wondering how to go from a 100m to a 400m the equation is this:

100m x 4.4913188625 = 400m
400m ÷ 4.4913188625 = 100m
