Question 587424
For most flying creatures, the length of the wing varies inversely as the number of wingbeats per second.
 A dragonfly has a winglength of 1.6 inches and a wingspeed of 45 times per second. 
If a bee has a wingspeed of 200 beats per second, what is the length of a bee's wing?
:
{{{b/1.6}}} = {{{45/200}}}; varies inversely
Cross multiply
200b = 1.6 * 45
200b = 72
b = {{{72/200}}}
b = .36 inch is the bee's wing
