Since Mr. Smith leaves 3 hours before Mrs. Smith, Mr. Smith is $\"65%2A3=195\"$ miles ahead when Mrs. Smith leaves. Since Mrs. Smith travels 15 mph faster than Mr. Smith, every hour, Mrs. Smith gets 15 miles closer to Mr. Smith. Therefore, it will take Mrs. Smith $\"195%2F15=highlight%2813%29\"$ hours to catch up. \n" ); document.write( "
