Answer:
x = 6
Step-by-step explanation:
y varies inversely as x
y = k × 1/x. {where k is a constant}
when y = 3, x = 8
Therefore 3 = k/8 and k is 24
y = 24/x
When y = 4,
4 = 24/x
4x = 24
(dividing both sides by 4)
x = 6

Answer: She would have to burn between 220 and 240 calories per minute to have a calorie burn rate between those of Martin and Paul.
Step-by-step explanation:
Martin:
360 calories / 30 min = 12 calories/min
Paul:
165 calories / 15 min = 11 calories/min
Kara:
Needs to burn between 11 and 12 calories/min, so we'll calculate the range:
11 calories/min x 20 min = 220 calories (minimum # calories she can burn)
12 calories/min x 20 min = 240 calories (maximum # calories she can burn)
