Two cars pass on a straight highway while traveling in opposite directions. One car is traveling 6 mph faster than the other car. After 1.5 hours the two cars are 171 miles apart. Find the speed of each car. Show work
\n" ); document.write( "----
\n" ); document.write( "1st car DATA:
\n" ); document.write( "time = 1.5 hrs ; rate = x mph ; distance = r*t = 1.5x miles
\n" ); document.write( "----
\n" ); document.write( "2nd car DATA:
\n" ); document.write( "time = 1.5 hrs ; rate = x+6 mph ; distance = r*t = 1.5x+9 miles
\n" ); document.write( "-----
\n" ); document.write( "Equation:
\n" ); document.write( "dist + dist = 171 miles
\n" ); document.write( "1.5x + 1.5x+9 = 171
\n" ); document.write( "3x = 162
\n" ); document.write( "x = 54 mph (slower car speed)
\n" ); document.write( "x+6 = 60 mph (faster car speed)
