Work with your group members to solve the following problems. You may find that setting up proportions is helpful. For problems 1 through 4, assume a 150-pound person.
Q1. If a person jogs at a rate of 5 mi/h for 3 h in a week, how many calories do they burn?
Q2. If a person runs in place for 15 minutes, how many calories will be burned?
Q3. Ifapersoncross-countryskis for35minutes,how many calories willbeburned?
Q4. How many hours would a person have to jump rope in order to lose 1 pound? (Assume calorie consumption is just enough to maintain weight, with no activity.) Heavier people burn more calories (for the same activity), and lighter people burn fewer. In fact, you can calculate similar figures for burning calories by setting up the appropriate proportion.
Q5. At what rate would a 120-pound person burn calories while bicycling at 12 mi/h?
Provide complete and step by step solution for the question and show calculations and use formulas.
