NPR Sunday Puzzle (July 24) - Traveling the Periodic Table

NPR Sunday Puzzle (July 24) - Traveling the Periodic Table
Q: A 10-letter word for a form of travel, that consists of five consecutive symbols of chemical elements. What is it? If automobile had been the answer, Au, would represent Gold, Mo would represent Molybdenum, and Bi, would represent Bismuth. Unfortunately, the remaining bigrams, To and Le, are not chemical symbols.
To solve this puzzle, it really helps to have a List of the elements by chemical symbol. I'm not going to give away my answer yet, but I will tell you that I did try land travel (motorcycle, snowmobile), water travel (bathyscaph, hovercraft) and even animals (rhinoceros) before I came to the correct answer. Note: as much as I wanted it to, nothing starting with "Police" worked.
Edit: Time to reveal my answer. It wasn't land or water, so that leaves air...
He = Helium
Li = Lithium
Co = Cobalt
Pt = Platinum
Er = Erbium

NPR Sunday Puzzle (July 3) - Three Coins

NPR Sunday Puzzle (July 3) - Three Coins
Q: An imaginary country mints coins in three denominations. Each denomination has an integral number, 1, 2, 3, etc. The amounts, 20, 23 and 29, can each be made with exactly three coins. What are the three denominations minted?
Since the deadline has passed, I can tell you my answer to the puzzle. I arrived at this answer with a little bit of experimentation and algebra. If you don't want the answer, stop reading.

A: Assume a, b and c are integers.
Let's try the following equations:

1) a + b + b = 20
2) a + a + c = 23
3) b + c + c = 29

Combining #1 and #2 we have:
2a + c = 23
2a + 4b = 40
4) 4b - c = 17

Next combining #3 and #4 we have:
4b - c = 17
4b + 8c = 116
9c = 99
5) c = 11

Combining #3 and #5 we have:
b + 22 = 29
6) b = 7

Combining #1 and #6 we have:
a + 14 = 20
7) a = 6

Thus the coins are 6, 7 and 11
6 + 7 + 7 = 20
6 + 6 + 11 = 23
7 + 11 + 11 = 29

Edit: 5, 9, 10 was given as another acceptable answer (using 2a + c = 20, 2b + a = 23, 2c + b = 29), but I personally don't like it. I read the question as if each combination could only be made with 3 coins, not more nor less. 20 could be made with two "dimes" or four "nickels" rather than 5+5+10. However, I guess it technically answers the puzzle question which is why they must have decided to allow it. I think 6, 7, 11 must have been the intended answer.
