## 211. Math Puzzle 12/82

In the 1000-m race, Sven finished in 6:20.2 min, 0.2 seconds faster than Dirk.

How far apart were the two runners at the finish line?
The distance between the two runners at the finish line is calculated as $\Delta x=v \cdot \Delta t$. The time over $1000 \mathrm{~m}$ is 6:20.2 $=380.2$ seconds, $t=0.2$ seconds.

Thus $x=\frac{1000}{380.2} \cdot 0.2=0.526 \mathrm{~m}$. Sven was about $0.5 \mathrm{~m}$ ahead of Dirk at the finish line.
