An airplane traveled 2,000 miles in the same time that a car traveled 300 miles.
\n" ); document.write( " If the rate of the plane is 340 miles per hour greater than the rate of the car,
\n" ); document.write( " find the rate of the car.
\n" ); document.write( ":
\n" ); document.write( "Let r = rate of the car
\n" ); document.write( "then
\n" ); document.write( "(r+340) = rate of the plane
\n" ); document.write( ";
\n" ); document.write( "Times are equal, write a time equation; Time = \"dist%2Frate\"
\n" ); document.write( "\"2000%2F%28r%2B340%29\" = \"300%2Fr\"
\n" ); document.write( "Cross multiply
\n" ); document.write( "2000r = 300(r+340)
\n" ); document.write( ":
\n" ); document.write( "2000r = 300r + 102000
\n" ); document.write( ":
\n" ); document.write( "2000r - 300r = 102000
\n" ); document.write( ":
\n" ); document.write( "1700r = 102000
\n" ); document.write( "r = \"102000%2F1700\"
\n" ); document.write( "r = 60 mph is the car
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution by finding the times
\n" ); document.write( "300/60 = 5hr
\n" ); document.write( "2000(60+340) = 5hr\r
