It takes 305km to drive to location A from your house. You estimate you drove at an average speed of 80KPH. It takes you 4 hours and 10 minutes to get to location A. How many hours were you NOT driving?
\n" ); document.write( "======================================================
\n" ); document.write( "The total time for the trip will be equal to the time spent driving plus the time spent NOT driving
\n" ); document.write( "Let t = the time spent not driving
\n" ); document.write( "The time spent driving will be the distance traveled divided by the average driving speed:
\n" ); document.write( "Driving time = 305 km/80 kph = 3.8125 h
\n" ); document.write( "The total time for the trip = 4 h 10 min, so we can solve for t:
\n" ); document.write( "t = 4 1/6 h - 3.8125 h = 0.354 h = 21.25 min
\n" ); document.write( " \n" ); document.write( "
\n" );
