The ordinates of a $1$-hour unit hydrograph $\text{(UH)}$ are given below.
| Time (hours) | $0$ | $1$ | $2$ | $3$ | $4$ | $5$ |
| Ordinates of $1$-hour $\mathrm{UH}\left(\mathrm{m}^{3} / \mathrm{s}\right)$ | $0$ | $13$ | $50$ | $80$ | $95$ | $85$ |
| Time (hours) | $6$ | $7$ | $8$ | $9$ | $10$ | $11$ |
| Ordinates of $1$-hour $\mathrm{UH}\left(\mathrm{m}^{3} / \mathrm{s}\right)$ | $55$ | $35$ | $15$ | $10$ | $3$ | $0$ |
These ordinates are used to derive a $3$-hour $\text{UH}$. The peak discharge (in $\mathrm{m}^{3} / \mathrm{s}$ ) for the derived $3$-hour $\text{UH}$ is $\_\_\_\_\_\_\_$ (rounded off to the nearest integer).
