First, we need to determine how many times a hummingbird flaps its wings in one second. Since it flaps its wings 5,000 times in a minute, we can convert that to seconds as follows:
1 minute = 60 seconds
So, the number of flaps per second is:
\[ \text{Flaps per second} = \frac{5000 \text{ flaps}}{60 \text{ seconds}} \approx 83.33 \text{ flaps/second} \]
Now, to find out how many times it flaps its wings in 15 seconds, we multiply the number of flaps per second by the number of 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 1,250 times in 15 seconds.
