Final answer:
To calculate the number of calories burned, multiply the power output (in watts) by the time (in hours). The instructor burns 217.5 Calories during this time.
Step-by-step explanation:
To calculate the number of calories burned, we need to use the formula: calories burned = power output (in watts) x time (in hours)
Given that the Peloton instructor maintains an average power output of 435 W for 30.0 minutes, we need to convert the time to hours: 30.0 minutes = 30.0 / 60 = 0.5 hours.
Now we can calculate the calories burned: calories burned = 435 W x 0.5 hours = 217.5 Calories.
