I traveled from Vertex Valley to Fraction Falls last week. I completed 3/5 of the distance in the morning and 2/3 of the remaining distance in the afternoon. I still had 12 miles to travel. What is the distance from Vertex Valley to Fraction Falls?

3/5 + 2/3 * 2/5 = 13/15

so 2/15 x = 12
No go for it.
