A12 NM earlier.

Step one: The problem has already provided you with one part of the solution: you have a 90-knot tailwind component during the descent.

Step two: For a descent of 24,000', we will estimate a descent time of 8 minutes (assuming an average rate of descent of 3,000 fpm).

Step three: The adjusted distance equals the distance traveled in 8 minutes at a speed of 90 knots. Or, 8 minutes at 1.5 NM per minute, which equals 12 NM. In this case, since it is a tailwind, we would start down 12 NM earlier than was originally computed.
