traveled 62 miles in 4 hours. some time was biking @ 20mph. the other time spent running @ 8 mph. What is the distance traveled biking? What is the distance traveled biking in the 4 hours if traveled 62 miles
\n" ); document.write( "----
\n" ); document.write( "biking DATA:
\n" ); document.write( "distance = x ; rate = 20 mph ; time = x/20 hrs
\n" ); document.write( "----
\n" ); document.write( "running DATA:
\n" ); document.write( "distance = 62-x miles ; rate = 8 mph ; time = (62-x)/8 hrs
\n" ); document.write( "--------
\n" ); document.write( "Equation:
\n" ); document.write( "time + time = 4 hrs
\n" ); document.write( "x/20 + (62-x)/8 = 4
\n" ); document.write( "Multiply thru by 40 to get:
\n" ); document.write( "2x + 5*62-5X = 160
\n" ); document.write( "-3x = -150
\n" ); document.write( "x = 50 miles (biking distance)
\n" ); document.write( "---
\n" ); document.write( "62-x = 12 miles (running distance)
