The arithmetic mean, A, of any two positive numbers x and y is defined to be A=12(x+y) and their geometric mean, G, is defined to be G=xy. For two particular values x and y, with x>y, the ratio A:G=5:4. For these values of x and y, what is the ratio x:y?

hello, sorry being so rude after all that fighting i found it kind of funny, so as me saying sorry here is an answer!

since the table showed her that   2km = 2000m.

to determine, how many km in 2000m, she would divide by 1000.

= 2000 / 1000 = 2 km.

similarly, for 8000m = 8000 / 1000 = 8 km

cheers to savings
