A flight is plotted on a map having the scale 1 inch=400 miles. On the map it is 9-1/2 inches from point A to point B. If a plane flies this distant at the speed of 300 mph, how long will the trip take

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.

The linear equation is: y=ax+b

Lines that intersect at one point
