3. manuel is riding his bike. the graph represents the distance manuel travels from his house over time.
here is the
describe what is happening as depicted in the graph.

The first leg of the graph represents Manuel riding his bike for 3 units of time going 5 units distance gradually increasing his speed.  The second line segment represents Manuel staying where he his for 4 1/2 units of time.  The third represents Manuel going a fast speed back to where he started.  I think.

Or the first is him going that distance picking up speed, the second him going a constant speed, and the third him slowing down/speeding up.

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
