Answer:
40 miles
Explanation:
If Nicole has driven 20 miles and this is only half the distance, then the total length of her drive would be 40 miles.
We can determine this with a simple algebraic equation:
Let x be the total length of her drive.
We know that Nicole has already driven one-half of the distance, which can be represented as:
20 = 1/2x
Multiplying both sides by 2, we get:
40 = x
Therefore, the total length of Nicole's drive is 40 miles.
