Question

4. You want your 80 kg client to expend 2000 calories per week on a stationary bike. If she exercises at 1200 kgm/min, how many minutes per week must she exercise?

Answer 1

To burn 2000 calories at a rate of 1200 kgm/min, the client will need to exercise for approximately 712 minutes per week.

Step-by-step explanation:

First we need to convert 2000 calories into kilogram meter (kgm). 1 cal = 427 kgm, so 2000 cal = 854000 kgm. Now, we know that the client exercises at 1200 kgm/min. Thus, the time (t) in minutes it takes for the client to burn 2000 calories is equal to the total energy expended (854000 kgm) divided by the rate of energy expenditure (1200 kgm/min). So, t = 854000 kgm / 1200 kgm/min = 711.67 minutes, which rounds to approximately 712 minutes.
