John and Fawn, each drinking at a constant pace, can finish a case of soda together in 12 hours. How fast can John, drinking alone, finish the case?

1) The average time it would take both to finish independently is 30 hours.
2) It would take John 10 more hours to finish the case drinking alone than it would for Fawn to finish the case.

This is actually from MGMAT flash cards. Looked interesting and hence I posted after modifying it a bit (I added a new statement).

Answer: B
