Well based on the limited info yeah maybe....

Does it go away over 20? Does it sound like grinding or just a metal on metal scrap such as a heat shield...

[MikeMike89]

yeah, it sounds more like a heat shield scraping but it has drum brakes in the rear. and it dosnt do it at very low speeds

Without actually hearing the noise, I would say to look for a binding/dragging brake shoe. Does it make any noise while backing up?
