Brian drives 117 miles to the city. On the drive back home, his average speed decreases by 6 miles per hour.
\n" ); document.write( "Write two equations (for time, in hours) to the city and back home where \"r\" is the average speed (in miles per hour) when driving to the city.
\n" ); document.write( "-------
\n" ); document.write( "To city DATA:
\n" ); document.write( "distance = 117 miles ; rate = r mph ; time = d/r = 117/r hrs
\n" ); document.write( "-----
\n" ); document.write( "From city DATA:
\n" ); document.write( "distance = 117 miles ; rate = r-6 mph ; time = 117/(r-6) hrs
\n" ); document.write( "-----
\n" ); document.write( "Equations:
\n" ); document.write( "Time to city = 117/r hrs
\n" ); document.write( "----
\n" ); document.write( "Time from city = 117/(r-6) hrs
