Now you crosss multiply and divide...
6 * 1 = 6

I can not see your choices but I'm assuming that this equation is what you are looking for: 16t+vt+ho. The other equation 4.9t+vt+ho is used for meters. I apologize if those weren't your choices as once again I can not see them.
C. 17 r 1 is the correct answer
Your system could be anything, just remember that input should be half than the output.
So, y ≥ 1/2x
5y ≥ 5/2x
10y ≥ 5x
Hope this helps!
