Answer 1

From the table provided

Lion heart rate is 40 beats every minutes

Giraffe 5 beats every 12 seconds

Hummingbird 41 beats every 10seconds

Heart Rate = beat / time

For Lion

Beats = 40

time = 60 seconds

Heart rate for lion = 40/60

= 0.66 beat per second

For Giraffe

Rate = beat / time

Beats = 5

Time = 12 seconds

= 5/12

= 0.42 beat per second

For Hummingbird

Rate = beat / time

Beats = 41

time = 10seconds

= 41/10

= 4.1 beats per second

Lion = 0.66 beat per second

Giraffe = 0.42 beat per second

Hummingbird = 4.1 beat per second

Therefore, Giraffe has the slowest heart rate with 0.42 beat per second

The answer is giraffe
