Respuesta :

Answer:

Explanation:

Given

Weight of Mark [tex]= 254[/tex] pounds

Rate at which Mark burns calories [tex]= 1.2[/tex]kcal/pound/hour

Total time in one week in terms of hours [tex]= 45 * 7[/tex] minutes

[tex]= 315[/tex] minutes

Number of hours in [tex]315[/tex] minutes is equal to

[tex]\frac{315}{60} \\= 5.25[/tex] hours

So, the total number of calories burned by Mark in one week

[tex]= 1.2 * 5.25 * 254\\= 1600.2[/tex] calories
