A remote-control car races straight down the street at 18 feet per second. Two seconds later, a second remote-control car races straight down the same street at 36 feet per second. How long will it take the second car to catch up to the first car?
\n" ); document.write( " -----------
\n" ); document.write( "slower car DATA:
\n" ); document.write( "rate = 18 ft/sec ; time = t seconds ; distance = 18t ft
\n" ); document.write( "-------
\n" ); document.write( "faster car Data:
\n" ); document.write( "rate = 36 ft/sec ; time = t-2 seconds ; distance = 36(t-2) ft
\n" ); document.write( "------
\n" ); document.write( "Equation:
\n" ); document.write( "distance = distance
\n" ); document.write( "18t = 36t-72
\n" ); document.write( "18t = 72
\n" ); document.write( "t = 4 seconds
\n" ); document.write( "Ans: t-2 = 2 seconds
