For these kinds of problems, focus on getting one unit, and then do the other one.
Since there are 60 seconds in a minute, 39 feet per minute=39/60 or 13/20 feet per second.
Since there are 3 feet in a yard, 13/20 feet per second =13/60 yards per second.
The answer is 13/60 yards per second.
Hope this helps!

Step-by-step explanation:
If I have 90 pounds shared between A, B, and C, then in a mathematical equation,
A + B + C = 90
However, we have way too many unknowns.
We are told that the ratio of A to B is 1 to 2, or
and cross multiplying,
2A = B or ![A=\frac{1}{2}B](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B2%7DB)
We are also told that the ratio of B to C is 4 to 3, or
and cross multiplying,
3B = 4C or ![C=\frac{3}{4}B](https://tex.z-dn.net/?f=C%3D%5Cfrac%7B3%7D%7B4%7DB)
Now we have everything in terms of B, so we will rewrite it like that:
, and
and
9B = 360 so
B = 40. If B is 40 and A is half of B, then A is 20.
