Calculate the average metabolic rate of a person who sleeps 8.0 h, sits at a desk 8.0 h, engages in light activity 4.0 h, watches television 2.0 h, plays tennis 1.5 h, and runs 0.5 h daily.

The average metabolic rate of the person is 4 h daily

Explanation:

Average metabolic rate = sum of time for daily activities ÷ number of daily activities

sum of time of daily activities = 8 h + 8 h + 4 h + 2 h + 1.5 h + 0.5 h = 24 h

number of daily activities = 6

Average metabolic rate = 24 h ÷ 6 = 4h daily.

The average metabolic rate is 25% (6/24)

Explanation:

In this context, the metabolic rate is the percentage of time, out of 24 hours in which a person spends to do physical activities (light to intense).

from the information given, the time spent to do physical activities or exercises are;

light activity = 4 hours

play tennis = 1.5 hours

running = 0.5 hours

Total = 4 + 1.5 + 0.5 = 6 hours.

total over time in the day = 24 hours

therefore daily metabolic rate = 6 ÷ 24 = 0.25 = 25/100 = 25%
