Answer:

1600.2 calories

Explanation:

Given

Weight of Mark = 254 pounds

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

Total time in one week in terms of hours = 45 * 7 minutes

= 315 minutes

Number of hours in 315 minutes is equal to

\frac{315}{60} \\= 5.25 hours

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

= 1.2 * 5.25 * 254\\= 1600.2 calories
