1010 beats per minute, which is
20
%
20%, percent of its normal value.
What is a grizzly bear's normal heart rate when not hibernating?

Answer 1

If the heart rate of a grizzly bear is 10 bpm while hibernating and that is 20% of its heart rate then the heart rate of a grizzly bear in its normal state without hibernating is 50 bpm

Explanation:

Set up a ratio

10 bpm = 20%

x bpm = 100%

100/20 = 5

10 x 5 = 50 bpm
