Answer:
700 kilo calories was burnt during the entire race.
172.41 grams of pasta would provide him with 700 kcal energy.
Explanation:
Rate of burning calories = R = 10 kcal/min
Number of calories burnt in 1 hour and 10 minutes = x
Duration of race = t = 1 hour + 10 min
1 hour = 60 minutes
t = 60 min + 10 min = 70 min
[tex]x=R\times t=10 kcal/min\times 70 min=700 kcal[/tex]
700 kilo calories was burnt during the entire race.
Number of calories in 1 gram of pasta = 4.06 kcal/g
Amount of pasta with 700 kcal = m
[tex]m\times 4.06 kcal/g=700 kcal [/tex]
[tex]m=\frac{700 kcal}{4.06 kcal/g}=172.41 g[/tex]
172.41 grams of pasta would provide him with 700 kcal energy.
