Final answer:
Time ranges when mentioned in health, such as 1-2 times per day, indicate minimum and maximum frequency for an activity within a day. Averaging out calories used over different days is an example of working with time ranges to monitor health.
Step-by-step explanation:
When monitoring health, understanding and processing time ranges is important. For example, if you're advised to do an activity 1-2 times per day, it means that the activity should be done at least once, but no more than twice within a 24-hour period. In a health context, this could refer to taking medication, physical exercises, or meals. Similarly, when you are calculating the average calorie consumption, you would record the calories used across specified time ranges, such as a weekday and weekend day, and then average them out. For instance, in Step 2, you divide the total energy used in 2 days by 2 to calculate the daily average. This is a simple method for understanding patterns in your calorie usage. Step 3 emphasizes the importance of considering the scale of time units when interpreting results. It helps illustrate how larger or smaller units of time, like days and seconds, can impact our perception of quantities, such as the number of seconds in a day.
