\n" ); document.write( "How long will your friend wait for you at the end of the trip?
\n" ); document.write( "Answer in units of min
\n" ); document.write( ":
\n" ); document.write( "Let w = time your friend waits for you
\n" ); document.write( "Find the time required by each of you to go 63 km, ans will be in hrs, convert to min, mult by 60.
\n" ); document.write( ":
\n" ); document.write( "w = \"63%2F89.7\" - \"63%2F97\"
\n" ); document.write( "w = .70234 - .64948
\n" ); document.write( "w = .05285 * 60 = 3.17 minutes
