Trapezoidal Sum From Table Data

Question

The table shows the drainage rate, $$d(t)$$, in liters per minute, of a swimming pool at selected times $$t$$ in minutes.

| $$ t $$ (minutes) | 0 | 1 | 4 | 7 |
|-----------------|---|---|---|---|
| $$ d(t) $$ (L/min) | 20 | 32 | 16 | 8 |

Using a trapezoidal sum with the three subintervals given in the table, what is the approximate total volume of water, in liters, that drained from the pool from $$t=0$$ to $$t=7$$ minutes?
