Final answer:
The elephant's heart rate is calculated by dividing the total number of heart beats by the minutes observed. The calculation shows that the elephant's heart rate is 37.5 beats per minute, which is option (c).
Step-by-step explanation:
The question involves calculating an elephant's heart rate in beats per minute. To find the heart rate, we divide the total number of beats by the number of minutes. Since the elephant's heart beats 375 times in 10 minutes, we calculate the rate by dividing 375 beats by 10 minutes. The calculation is as follows:
Heart rate = Total beats ÷ Total minutes = 375 beats ÷ 10 minutes = 37.5 beats per minute.
Therefore, the correct answer to the question is 37.5 beats per minute, which corresponds to option (c).
