Hummingbirds beat their wings many times per second. Which equation relates the number of beats per second (a) to the number of wing beats per minute (b)? a = wings beats per second. b = wings beats per minute. A. b = 60/aB. b = a + 60C. b = a/60D. b = 60a
We know that 1 minute has 60 seconds. So, if a is the number of wings beats per second, then the number of wings beats per second will be 60 times a, so
