Two cars leave Denver at the same time and travel in opposite directions. One car travels 10mi/h faster than the other car. The cars are 50mi apart in 5h. How fast is each car traveling?
\n" ); document.write( "------
\n" ); document.write( "Let the speed of the slower car be x mph.
\n" ); document.write( "Then the speed of the faster car is x+10 mph.
\n" ); document.write( "----
\n" ); document.write( "The cars are separating at a combined speed of 2x+10 mph.
\n" ); document.write( "-----
\n" ); document.write( "Equation:
\n" ); document.write( "speed = distance / time
\n" ); document.write( "speed = 50 mi/5 hr
\n" ); document.write( "speed = 10 mph
\n" ); document.write( "---
\n" ); document.write( "2x+10 = 10
\n" ); document.write( "2x = 0
\n" ); document.write( "x = 0
\n" ); document.write( "x+10 = 10
\n" ); document.write( "---
\n" ); document.write( "One of the cars is not moving.
\n" ); document.write( "The other's speed is 10 mph.
