To find out how many times a hummingbird will flap its wings in 15 seconds, we can first calculate how many flaps it makes per second.
Given that the hummingbird flaps its wings 5,000 times per minute, we find the flaps per second by dividing by the number of seconds in a minute (60 seconds):
\[ \text{Flaps per second} = \frac{5000 \text{ flaps}}{60 \text{ seconds}} \approx 83.33 \text{ flaps per second} \]
Now, we can calculate the number of flaps in 15 seconds:
\[ \text{Total flaps in 15 seconds} = 83.33 \text{ flaps/second} \times 15 \text{ seconds} \approx 1250 \text{ flaps} \]
Therefore, the hummingbird will flap its wings approximately 1250 times in 15 seconds.
