Can't quite get the answer right

For question 1.39 in the 6th edition

I've been having serious issues getting the correct answer while using De Broglie's Equation. The conversions I've been using is the given 1 ounce = 28.3 grams, 1609 meters = 1 mile and 60 sec = 1 hour. The answer supplied at the back of the textbook lists it as 1.1 x 10^-34 m and I end up with 1.8 x 10^-36 m.

I've linked an image of my work for a visual; it also contains the text of the question.

I noticed that one of your conversion factors is 60sec/1hour when it should be 3600sec/1hour. I would try that and see if it gives you the right answer.
