Person A and person B start from the same location, at the same time. They ride their bikes in opposite directions for 3 hours, at which time they are 102 miles apart. person A rides 4 miles per hour faster than person B. Find the rate of each rider.
\n" ); document.write( "**
\n" ); document.write( "let x=rate of rider B
\n" ); document.write( "x+4=rate of rider A
\n" ); document.write( "distance=travel time*rate
\n" ); document.write( "..
\n" ); document.write( "3x+3(x+4)=102
\n" ); document.write( "3x+3x+12=102
\n" ); document.write( "6x=90
\n" ); document.write( "x=15
\n" ); document.write( "x+4=19
\n" ); document.write( "ans:
\n" ); document.write( "rate of rider B=15 mph
\n" ); document.write( "rate of rider A=19 mph
