Final answer:

In 10 minutes, a chicken's heart beats 2530 times more than a whale's heart. This can be calculated either by direct comparison or by finding the heartbeat difference per minute and then multiplying by 10 minutes.

Step-by-step explanation:

To find out how many more times a chicken's heart beats than a whale's heart in 10 minutes, we can use two methods.

  • Direct Comparison: Multiply the heart rate of each animal by the number of minutes (10) and then subtract the whale's total from the chicken's total.
  • For the chicken, 275 beats/min × 10 min = 2750 beats. For the whale, 22 beats/min × 10 min = 220 beats. Now subtract the whale's total from the chicken's total: 2750 beats - 220 beats = 2530 beats.
  • Heartbeat Difference per Minute: First, find the difference in heartbeats per minute between the two animals: 275 beats/min - 22 beats/min = 253 beats/min.
  • Then multiply this difference by the number of minutes: 253 beats/min × 10 min = 2530 beats.

In both methods, we find that in 10 minutes, a chicken's heart beats 2530 times more than a whale's heart.
