Energy Rates:
Swimming:
600/4.5=133.3
Running:
900/30=30
Cycling:
1100/15=73.3
Speed multiplied by the calories per km:
Swimming:
A=4.69x133.3=625.17
B=4.17x133.3=555.86
C=3.95x133.3=526.53
Running:
A=18.51X30=555.30
B=18.86X30=565.80
C=20X30=600.00
Cycling:
A=37.03X73.3=2714.29
B=36.70X73.3=2690.11
C=37.73X73.3=2765.60
In Swimming:
A=625.17X0.32=200.05
B=555.86X0.36=200.10
C=526.53X0.38=200.08
In Running:
A=555.3X0.53=294.30
B=565.80X0.52=294.22
C=600.00X0.50=300.00
In Cycling:
A=2714.29X1.073=2912.44
B=2690.11X1.088=2926.84
C=2765.60X1.53=2912.18
The Answers:
Adam:200.05+294.30+2912.44=3406.79
Ben:200.10+294.22+2926.84=3407.16
Charles:200.08+300+2912.18=3412.26
