Given the constraints, let's calculate the number of stickmen who will live to see dry land within the given 20 minutes.

1. Each round trip takes 9 minutes.
2. Each trip can save 5 stickmen.

The number of full round trips possible in 20 minutes is:

\[ \left\lfloor \frac{20}{9} \right\rfloor = 2 \]

In these 2 round trips, the number of stickmen saved is:

\[ 2 \times 5 = 10 \]

So, 10 stickmen can be saved.

The remaining stickmen who cannot be saved are:

\[ 15 - 10 = 5 \]

Therefore, **10** stickmen will live to see dry land.
