Question

(WILL GIVE BRAINLIEST ANSWER) A runner burns 10 kilocalories per minute. If the runner completes a race in 1 hour and ten minutes, how many kilocalories does he burn during the entire race? How many grams of pasta would provide him with this much energy? (1 gram of pasta gives 4.06 kilocalories of energy)

Answer 1

60 minutes in an hour so. 60 times 10=600+10 more minutes

He burns 610 kilocalories

Then 610 / 4.06

150.25

Answer 2

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

$x=R\times t=10 kcal/min\times 70 min=700 kcal$

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

$m\times 4.06 kcal/g=700 kcal$

$m=\frac{700 kcal}{4.06 kcal/g}=172.41 g$

172.41 grams of pasta would provide him with 700 kcal energy.
