When a grizzly bear hibernates, its heart rate drops to 10 beats per minute, which is 20 percent of its normal value.
50 bpm
To calculate the normal heart rate of a grizzly bear during hibernation, we can use the information that its heart rate drops to 10 beats per minute, which is 20 percent of its normal value.
First, let's represent the normal heart rate as "x". We can set up an equation to represent the given information:
10 = 0.2x
To solve for "x", we divide both sides of the equation by 0.2:
10 / 0.2 = x
This simplifies to:
50 = x
Therefore, the grizzly bear's normal heart rate during hibernation is 50 beats per minute.
