Insufficient as we do not know the distance.

(2) The route is 14 miles long.

Insufficient as we do not know Bill's speed.

Statement 1 and 2 together:

Time taken by Bill = Distance / Speed = 14/34 hours. Sufficient.

Information about Joe's speed is superfluous.

The correct answer: C

Hope this helps!
