# RE10 | anthropic/claude-opus-5 | run 1

## Prompt

You land at 1:35 PM with a connecting flight departing at 3:00 PM from the same airport. Clearing customs takes 25 minutes, the walk to your departure gate takes 15 minutes, and boarding closes 20 minutes before departure. Will you make the connection? Show your reasoning.

## Response

Yes — you make it with about 25 minutes to spare.

## Timeline

| Step | Duration | Clock time |
|---|---|---|
| Landing (touchdown) | — | 1:35 PM |
| Clear customs | 25 min | 2:00 PM |
| Walk to departure gate | 15 min | 2:15 PM |
| **Boarding closes** | — | **2:40 PM** |
| Scheduled departure | — | 3:00 PM |

## Reasoning

Total time needed after landing is 25 + 15 = 40 minutes, putting you at the gate at 2:15 PM.

Your hard deadline is boarding close, not departure: 3:00 PM minus 20 minutes = 2:40 PM.

Buffer = 2:40 PM − 2:15 PM = **25 minutes**.

## Caveats worth noting

The calculation assumes the clock starts at touchdown. In practice, taxiing to the gate and deplaning often add 10–20 minutes, which would cut your buffer to roughly 5–15 minutes.

It also assumes no checked-baggage recheck, no security re-screening after customs, and an on-time arrival — any of which can consume the remaining margin.

Would you like me to rerun the math with a specific taxi-and-deplaning delay or a late arrival scenario?
