Carlos can run to ingrids house in 30 minutes.
\n" ); document.write( " Ingrid can run to Carlos house in 40 minutes.
\n" ); document.write( "If they start from their houses at the same time, in how many minutes will they meet?
\n" ); document.write( ":
\n" ); document.write( "Let d = the distance between the house
\n" ); document.write( "Let t = travel time of both when they meet
\n" ); document.write( ":
\n" ); document.write( " $\"d%2F30\"$ + $\"d%2F40\"$ = $\"d%2Ft\"$
\n" ); document.write( "multiply by 120t, results
\n" ); document.write( "4dt + 3dt = 120d
\n" ); document.write( "7dt = 120d
\n" ); document.write( "divide both sides by d
\n" ); document.write( "7t = 120
\n" ); document.write( "t = $\"120%2F7\"$
\n" ); document.write( "t = 17.143 minutes travel time when they meet \n" ); document.write( "

\n" );
