Bickford traveled twice as fast as Shawn traveled. Thus, Bickford could travel the 320 miles to the reef in only 2 hours less than it took shawn to travel the 240-miles to Jane's house. Find the rates and times of both boys.
Just having problems figuring out the formula and how to set it up...
thanks guys, i was thinking that, but in the question it was dealing with string vibrations were 1050hz and 2700hz and 1mm..
original question:
(1050)(/sqrt 1)=(2700)(/sqrt D)
got to that last part and forgot what to do so i did it like this:
if 1mm equals 1050hz - then 1/1050 would equal...
Such a simple problem that I am stuck on...
1050=2700 /d
0.388=/d
how do i get "d" by itself? ( the "/" is square root not divide)
edit: is "D" diameter or distance... one is "d" and other is "D"
