Question

A personal trainer designs exercise plans based on a combination of strength-training and aerobic exercise. A beginner plan has 15 minutes per session of strength-training and 20 minutes per session of aerobic exercise for a total of 90 minutes of exercise in a week. An advanced plan has 20 minutes per session of strength-training and 30 minutes of aerobic exercise for a total of 130 minutes of exercise in a week.

Answer 1

Which statement describes when the plans are based on the same number of aerobic exercise sessions?

a.Each plan utilizes a combination of 2 strength-training sessions and 2 aerobic exercise sessions per week.
b. Each plan utilizes a combination of 2 strength-training sessions and 3 aerobic exercise sessions per week.
c. Each plan utilizes a combination of 3 strength-training sessions and 2 aerobic exercise sessions per week.
d. Each plan utilizes a combination of 3 strength-training sessions and 3 aerobic exercise sessions per week.

Answer 2

For a beginner like you :
Strength training = x
Aerobics = y
15x + 20y = 90

For Ultimate warriors (me):

20x + 30y= 130

Test with the given values:

15 * 2 + 20 * 3 = 90 = R.H.S

20 * 2 + 30 * 3 = 130 = R.H.S
