Question

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

Answer 1

Answer:

50 beats per minute

Step-by-step explanation:

20x5=100

So...

10x5=50

Answer 2

Let the normal heart rate be x.

20% of x = 10 beats per minute

$\frac{20}{100} \times x = 10$

$x = 10 \times \frac{100}{20}$

$x = 50$

Therefore the normal heart rate of the grizzly bear is 50 beats per minute.
