If Mark is traveling South at 10 miles per hour for 45 minutes,
\n" ); document.write( " and Sally is traveling North at 5 miles per hour for 30 minutes,
\n" ); document.write( " and they meet after one hour, how far apart were they when they began?
\n" ); document.write( ":
\n" ); document.write( "The distance they were apart will equal the total distance they traveled.
\n" ); document.write( ":
\n" ); document.write( "Write a distance equation; d = speed * time
\n" ); document.write( ":
\n" ); document.write( "Change 45 min to .75 hrs, and 30 min to .5 hrs
\n" ); document.write( ":
\n" ); document.write( "d = 10(.75) + 5(.5)
\n" ); document.write( "d = 7.5 + 2.5
\n" ); document.write( "d = 10 mi apart
\n" ); document.write( ":
\n" ); document.write( "Not sure how \"they meet after one hour\" fits into this \n" ); document.write( "

\n" );
