1-37.

The area represents distance traveled (or displacement) between x = 0 and x = t.

The shape is a trapezoid.

$\text{base_1 and base_2 are vertical, so they represent velocity \left(in\ \frac{miles}{hour}\right).}$

Height is horizontal, so it represents time, in hours. Evaluate the area of a trapezoid. Simplify the units.

Find A (20x + 30, 0 ≤ x ≤ 2).

Use the eTool below to set values for t.
