8-144.

$\int _ { 3 } ^ { 8 } H ( t ) d t = - 1.25$ where $H$ represents the rate that snow accumulates on a certain day in January. $H$ is measured in feet per hour and $t = 0$ represents 12:00 p.m. Homework Help ✎

1. Write a complete description about what the integral is computing. Use correct units and be sure to mention the meaning of the bounds in your description.

If H is measured in feet per hour and $t$ is in hours, what are the units of the area under the curve?

2. Compute the value of $\frac { 1 } { 5 } \int _ { 3 } ^ { 8 } H ( t ) d t$ and interpret its meaning in the context of this situation.

Look at the bounds of integration. Where does the $1/5$ come from?
