Answer:
Average Power = 697 watts
Step-by-step explanation:
Given : 100 Calories used in 1 mile and you run in 10 minute
miles
To find : What is your average power output, in watts, during a 1 hour run
Solution : In 10 minutes 100 calories consumes per mile
So, In 1 min = [tex]\frac{100}{10}=10[/tex] calories consume
Now, in 1 hour = 60 minutes
So, In 60 min = [tex]{10}\times{60}=600[/tex] calories consume.
The conversion S.I unit is [tex]4.18\times10^3 J/cal[/tex]
Energy 600 cal = [tex]600 cal\times4.18\times10^3 J/cal= 2.508\times 10^6J[/tex]
Time taken 1 hour = 3600 seconds
Average power =[tex]\frac{\text{Energy}}{\text{Time taken}}[/tex]
Average Power =[tex]\frac{(2.508\times 10^6 J)}{3600 s}[/tex]
Average Power = 697 watts
