\n" ); document.write( "sarah is traveling from city A to b. the distance between these 2 cities is 185 miles and she planned to arrive at city b in 2 hrs 30 minutes. her average speed for the first 1 hr 40 minutes was 75 miles per hour. but then she realized she should slow down to dive more safely. if she still wanted to arrive at her destination on time , at what speed should she drive.
\n" ); document.write( "
Driving for 1 hr 40 minutes at 75 mph means that she covered a distance of \"75%281%262%2F3%29\", or \"75%285%2F3%29\", or 125 miles
\n" ); document.write( "This means that she still has 60 (185 - 125) miles to cover in 50 minutes (\"2%261%2F2+-+1%262%2F3\") hours, or \"5%2F6\" hour
\n" ); document.write( "Therefore, she has to drive at a speed of: \"60%2F%285%2F6%29\", or \"60+%2A+%286%2F5%29\", or \"highlight_green%2872%29\" mph \n" ); document.write( "
\n" );
