\n" ); document.write( "Jerry had a doctor's appointment at 10:00 am. The doctor's office is located 16.2 miles away from Jerry's house. John got in the car at 9:30 am, drove with an average speed of 25.4 mph.
\n" ); document.write( "Jerry ended up being late for the appointment. How much faster should he have driven (in mph).
\n" ); document.write( "
\"Speed+=+Distance%2FTime\"
\n" ); document.write( "Time to get there: 30 minutes, or \"1%2F2\" hour
\n" ); document.write( "Speed at which he needs to drive to get there in exactly 30 minutes: \"Speed+=+16.2%2F%281%2F2%29\", or 32.4 mph
\n" ); document.write( "Actual speed he traveled at to get there late: 25.4 mph.
\n" ); document.write( "So, he should've travelled at least \"highlight_green%287%29\" (32.4 - 25.4) mph faster to get there in EXACTLY 30 minutes, or \"1%2F2\" hour \n" ); document.write( "
\n" );
