document.write( "Question 1021980: The distance to Arsh’s cottage is 230km. Part of the trip is spent driving on a paved road where the limit is 80km/h. The rest of the trip is spent driving on gravel road with the limit being 50km/h. If the trip takes 4 hours, how many hours are spent on each part? \n" ); document.write( "
