Two friends decide to meet in Chicago to attend a cubs game. Rob travels 96 miles in the same time that carl travels 75 miles. Robs trip uses more interstate highways and he can average 7mph more than Carl what is Robs Average speed
\n" ); document.write( "---------------
\n" ); document.write( "Rob DATA:
\n" ); document.write( "distance = 96 miles ; rate = x mph ; time = d/r=96/x hrs.
\n" ); document.write( "--------
\n" ); document.write( "Carl DATA:
\n" ); document.write( "distance = 75 miles: rate = x-7 mph ; time = d/r = 75/(x-7)
\n" ); document.write( "-----
\n" ); document.write( "EQUATION:
\n" ); document.write( "time = time
\n" ); document.write( "96/x = 75/(x-7)
\n" ); document.write( "96(x-7)=75(x)
\n" ); document.write( "96x-672 = 75x
\n" ); document.write( "21x=672
\n" ); document.write( "x=32 mph (Rob's speed)
\n" ); document.write( "x-7=25 mph (Carl's speed)
