A humming bird flaps its wings 5,000 times a minute how many times will it flap its wings in 15 seconds
To find out how many times a hummingbird will flap its wings in 15 seconds, we need to convert the number of flaps per minute to flaps per second.
There are 60 seconds in a minute, so one minute equals 60 seconds.
Therefore, if a hummingbird flaps its wings 5,000 times a minute, it will flap its wings 5,000/60 = 83.33 times per second.
So in 15 seconds, the hummingbird will flap its wings 15 * 83.33 = 1250 times. Answer: \boxed{1250}.
