document.write( "Question 399194: Caroline covers 1200 miles on her business trip driving on a combination of snowy roads and ice-free ploughed roads one winter. Her average speed on the snowy roads is 40 mph while she maintains 60 mph on the ice-free pavement. If her driving time on the snowy road is 1/4 times that of the ice free road, how many hours has elapsed since Caroline left home?\r
