The electrical resistance of the wire is proportional to its length L and inversely proportional to the square of its diameter, 
.
The length of the wire in the problem is changed from 200 inches to 500 inches, so the new length is 2.5 times the initial length:
the diameter of the wire is not changed, so the new electrical resistance must be 2.5 times the original value:
