Step 1
Since the graph forms a rectangle with a length of 2 and a height of 2, the total rainfall after 2 hours is 2 * 2 = 4 cm. Show more…

The rates at which rain fell, in inches per hour, in two different locations $ t $ hours after the start of a storm are given by $ f(t) = 0.73t^3 - 2t^2 + t + 0.6 $ and $ g(t) = 0.17t^2 - 0.5t + 1.1 $. Compute the area between the graphs for $ 0 \le t \le 2 $ and interpret your result in this context.

The rates at which rain fell, in inches per hour, in two different locations $t$ hours after the start of a storm were modeled by $f(t)=0.73 t^{3}-2 t^{2}+t+0.6$ and $g(t)=0.17 t^{2}-0.5 t+1.1 .$ Compute the area between the graphs for $0 \leqslant t \leqslant 2$ and interpret your result in this context.
A rainstorm hit Portland, Maine, in October 1996 , resulting in record rainfall. The rainfall rate $R(t)$ on October 21 is recorded, in centimeters per hour, in the following table, where $t$ is the number of hours since midnight. Compute the total rainfall during this 24 -hour period and indicate on a graph how this quantity can be interpreted as an area. $$ \begin{array}{|l|cccccc|} \hline t(\mathrm{~h}) & 0-2 & 2-4 & 4-9 & 9-12 & 12-20 & 20-24 \\ \hline R(t)(\mathrm{cm} / \mathrm{h}) & 0.5 & 0.3 & 1.0 & 2.5 & 1.5 & 0.6 \\ \hline \end{array} $$
