# RE8 | moonshotai/kimi-k3 | run 2

## Prompt

Minimize total time to finish these tasks, one at a time, respecting dependencies: A (2h, no deps); B (3h, needs A); C (1h, no deps); D (2h, needs B and C). Give a valid order and the total time.

## Response

Since tasks run one at a time with no idle time, the total equals the sum of all durations: 2 + 3 + 1 + 2 = **8 hours**, for any valid order.

## Valid Order

**A → B → C → D**

- A (2h): finishes at 2h
- B (3h, needs A): finishes at 5h
- C (1h): finishes at 6h
- D (2h, needs B and C): finishes at 8h

Other valid orders: A → C → B → D or C → A → B → D. All give 8 hours, since dependencies never force idle time (A and C are always available to start).

Would you like to see how this changes if tasks could run in parallel?
