\n" ); document.write( "I guess the question asked,\"How much the 2nd lap should be to have an average of 60mph?\" Then by Averaging,
\n" ); document.write( " $\"Ave=%28Lap%5B1%5D%2BLap%5B2%5D%29%2F2\"$
\n" ); document.write( " $\"60=%2830%2BLap%5B2%5D%29%2F2\"$ , cross multiply
\n" ); document.write( " $\"60%2A2=30%2BLap%5B2%5D\"$
\n" ); document.write( " $\"120-30=Lap%5B2%5D\"$
\n" ); document.write( " $\"highlight%28Lap%5B2%5D=90mph%29\"$ ---> to have an Average of 60mph in 2 Laps.
\n" ); document.write( "If the re-phrase question is what it is.
