Step-by-step explanation:
If x is directly proportional to y, then


where, k is constant of proportionality.
We know that,
1 miles = 1.60934 km
It is given that x-miles and y- kilometers. Constant of proportionality is 1.60934.

Hence, the required equation is
.
Just plug in -1 for x and u should get ur answer
I think the answer is 2x^3+10x^2-2x-10
