Answer: E 60 heartbeats
Nope, 45 heartbeats, I think.
x/12 = 60/16
16x = 720
x = 720/16 = 45
or
16 seconds for 12 heartbeats
1 second for 12/16 heartbeats
60 seconds for (12/16)(6) = 45 heartbeats
To find out how many heartbeats a lion will have in 60 seconds, we first need to find out the lion's heart rate per second.
We know that the lion's heart beats 12 times in 16 seconds. To find the heart rate per second, we divide the total number of heartbeats (12) by the total number of seconds (16).
Heart Rate per second = Total Heartbeats / Total Seconds
Heart Rate per second = 12 / 16
Heart Rate per second = 0.75 heartbeats per second
Now, to find out how many heartbeats the lion will have in 60 seconds, we multiply the heart rate per second by the total number of seconds.
Heartbeats in 60 seconds = Heart Rate per second * Total Seconds
Heartbeats in 60 seconds = 0.75 * 60
Heartbeats in 60 seconds = 45 heartbeats
Therefore, the lion will have 45 heartbeats in 60 seconds.
The correct answer is B) 45 heartbeats.
