Healthy enough in exerice should get either should get either 150 minutes of moderate physical activity (like walking or streching) per week or 75 minutes of vigorous activity (like running or hiking) per week. Let;s say that the gym at your campus has treadmilis, stationary bikes, and elliptical machines. You can choose none, some or all of those as part of a working plan. Write all the possible choices you could make, then explain what in the world that has in do with our study of sets in this lesson.

Answer 1

Treadmills = Walking or running
Stationary bikes = Cycling (qualifies as vigorous activity)
Elliptical Machines = Walking or running;

Possible choices:
1) 150 minutes of walking on treadmill
2) 75 minutes of running on treadmill
3) 75 minutes of cycling
4) 150 minutes of mild exercise on elliptical machines (qualifies as walking)
5) 75 minutes of heavy exercise on elliptical machines (qualifies as running)
6) 75 mins of walking on tread mill + 75 mins of mild exercise on elliptical machines

Three equipment available are three different sets have different values based on their intesity of exercise in time duration;
We have to choose those sets whose union turns out to be 75 mins of vigorous activity or 150 minutes of moderate activity;
