He notices that at 10:45 a.m. they are passing a marker labeled 101, and at 11:00 a.m. the car reaches marker 119. what is the speed?\r
\n" ); document.write( "\n" ); document.write( "since i had to figure out how this other guy got 18x4=72...i figure id explain why so people can actually understand how to solve this.\r
\n" ); document.write( "\n" ); document.write( "MILE markers from 101 to 119 means 18 miles in distance
\n" ); document.write( "Took them 15mins because 11:00am-10:45am=15mins
\n" ); document.write( "15 mins is 1/4th of 1hour
\n" ); document.write( "so 15(4)=1hr
\n" ); document.write( "so 18(4)=72miles\r
\n" ); document.write( "\n" ); document.write( "18miles/15mins => (18mi(4))/(15min(4))=>72mi/60mins=> 72mi/hr=> 72mph
\n" ); document.write( "
\n" );
