## 1. Aljmez

On the planet Aljmez, a day is called NAD, an hour is called TAS, a minute is called NIM, and a second is called KES. One NAD lasts ten TAS, one TAS lasts ten NIM, and one NIM lasts eight KES. How many Earth seconds does one Aljmezian KES last, if one NAD lasts as long as one day?

Result: $\quad \mathbf{1 0 8}$
## Solution.

$1 \mathrm{NAD}=10 \mathrm{TAS}=100 \mathrm{NIM}=800 \mathrm{KES}$

1 day $=24$ hours $=1440$ minutes $=86400$ seconds

Since 1 NAD and 1 day last the same, then 800 KES $=86400$ seconds, so it follows that:

$1 \mathrm{KES}=86400: 800=864: 8=108$ seconds
