What is the average metabolic rate for a boiler maker who is performing maintenance on the boiler during shutdown and works for 3 hours at 3.5 kcal/min, takes a break for 30 min in a sitting position (metabolic rate = 0.3 kcal/min), resumes working on the outside of the boiler for 3.5 hours (metabolic rate = 2.5 kcal/min), then performs administrative work in the area for 1 hour (metabolic rate = 0.4 kcal/min)?

The average metabolic rate for the boiler maker during the 8 hours is 2.475 kcal/min.

Step-by-step explanation:

We can calculate the average as a weighted average.

This weighted average can be expressed as:

being ti the hours on each task or break, and Mi the metabolic rate for each task or break.

The average metabolic rate for the boiler maker during the 8 hours is 2.475 kcal/min.

5/12, or 5: 12

step-by-step explanation:

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
