Answer:
286 minutes
Explanation:
Given the content of fat in a meal= 53g
the content of protien in a meal= 38g
the content of carbohydrate in a meal= 152g
Also given that fuel value of protien = 17 KJ/g
the fuel value of fat = 38 KJ/g
the fuel value of carbohydrate = 17 KJ/g
Now to burn all the molecules the energy recquired is content of molecule times the fuel value.
the energy recquired to burn fat =
the energy recquired to burn protien =
the energy recquired to burn carbohydrate =
The total energy=2014+646+2584=5244KJ
The energy spent on swimming is 1100KJ/hour
for 1 hour 1100 KJ are spent
to spend 5244 KJ of energy the time taken is = =4.76hours
We know 1 hour=60 minutes
The total time =
