Question

Denise wants to burn at least 5000 calories a week through running. Based on her running speed, she estimates that she can burn 550 calories per hour.
If Denise runs for one half hour each week day and one hour each weekend day, will she meet her goal? Justify your answer.

Answer 1

Answer:

She will not meet her goal.

Step-by-step explanation:

There are 5 weekdays, so she will run for 0.5 * 5 = 2.5 hours over the weekdays

There are 2 weekends, so she will run for 2 * 1 = 2 hours over the weekend.

In total, this means she will run for 4.5 hours.

4.5 hours * 550 calories per hour = 2475 calories.

She will not meet her goal.
