When a grizzly bear hibernates, it’s heart rate drops to 10 beats per minute, which is 20% of its normal value. what is a grizzly bear’s normal heart rate when not hibernating?

If something 20% of its normal value, then it has been divided by 5 (using the example of 100%, if you divide this by 5 it leaves you with 20%). This means that 10 beats per minute are only a fifth of its usual heart rate. Therefore a grizzly bear's normal heart rate is 10 × 5 = 50 beats per minute.
