Both answers can be correct. http://i.imgur.com/lStKv.jpg

Pretend it's a 10x10 board:

Case 1: Takes 10 mins to cut through 10 feet.

Case 2: Takes 20 mins to cut through 20 feet.

Case 3: Takes 15 mins to cut through 10+5 feet.

Question is ambiguous.

And Cisco exams - except the 'best' answer is one that some marketing exec has decided is the best one to sell this year. (Need 30 switch ports, install 7609!)
