First, we can factor this to make it easier to solve:
3(x^3 + 13x^2 + 13x + 9)
Now, we can use the rational root theorem like so:
List factors of 9:
1, 3, 9.
List factors of 1:
1
Because of this, we know our possible rational roots are:
+/-1, +/-3, +/-9
If none of these zeros fit using the remainder theorem, then we know our roots will be irrational.

If Lisa flies from SAN Francisco to New York (2500mi) in 5 hours and then flies from New York to Rome (3487.5 mi) at 465mph. The average speed for the entire trip is 482.5mph.
The best answer would be 55.5556 meters per second.
