Malcolm is driving 1,323 miles from Wichita to Charleston for a family reunion. He drives 443 miles the first day and 409 miles the second day. Round each distance to the nearest ten and estimate about how many miles Malcolm has left to drive.

Malcolm has driven a total of 443 + 409 = <<443+409=852>>852 miles.

Rounded to the nearest ten, Malcolm has driven 850 miles.
Malcolm has 1323 - 850 = <<1323-850=473>>473 miles left to drive.
Rounded to the nearest ten, Malcolm has about 470 miles left to drive. Answer: \boxed{470}.
