1 mile=1.6 kilometer aproximetly

put 2 istead of x

look f(x)=y so it is asking to you what is the y when x is 2 and if you will put istead x of any numbers like 1,2,3... you will find points of (x,y) and how graph is look like 

I think there is no answer :)

My question it was wrong:  2 [ R1 * R2]  and d all of it distances (just a stupid question:)

Thanks everybody, i understood everithing! exuse me for taking your times!

But can it be determined without puting any distance

thanks Hayley! :)

Yx62/100=93

find Y

my explonation so clear that nobody understood

perimeter = a+b+c
