5.4 kJ of energy are needed every hour for each kg of mass. James weighs 65 kg. Calculate his BER (Basic Energy Requirement) for a day.

a) 702 kJ
b) 352 kJ
c) 293 kJ
d) 218 kJ

Answer :

Final answer:

James' Basic Energy Requirement (BER) for a day is 8424 kJ.

Explanation:

To calculate James' Basic Energy Requirement (BER) for a day, we need to multiply the energy needed per hour (5.4 kJ/kg) by James' weight (65 kg) and then multiply the result by the number of hours in a day. So, the calculation would be:

BER = Energy needed per hour x James' weight x Number of hours in a day

BER = 5.4 kJ/kg x 65 kg x 24 hours

Simplifying the calculation, we get:

BER = 8424 kJ

Therefore, James' BER for a day is 8424 kJ.
