Answer: 45 times


Step-by-step explanation:

Given : A lion's heart beats 12 times in 16 seconds.

Let  the number of heart beats of lion  in 60 seconds be 'x'

As heart beats and time are directly proportional .

Thus, we get

[tex]\frac{x}{60}=\frac{12}{16}\\\\\Rightarrow\ x=\frac{12}{16}\times60\\\\\Rightarrow\ x=45[/tex]

Therefore, the lion's heart beats 45 times in 60 seconds.
