a local bus travels 7 mph slower than the express bus. the express travels 90 miles in the same amount of time it takes the local to travel 75 miles. find the speed of each bus.
\n" ); document.write( "-----------------------
\n" ); document.write( "Express bus DATA:
\n" ); document.write( "distance = 90 miles ; rate = x mph ; time = 90/x hrs.
\n" ); document.write( "-----------------------
\n" ); document.write( "Local bus DATA:
\n" ); document.write( "distance = 75 miles; rate = (x-7)mph ; time = 75/(x-7) hrs
\n" ); document.write( "--------------------------
\n" ); document.write( "Equation:
\n" ); document.write( "time = time
\n" ); document.write( "90/x = 75(x-7)
\n" ); document.write( "90(x-7) = 75x
\n" ); document.write( "90x-75x = 630
\n" ); document.write( "15x = 630
\n" ); document.write( "x = 42 mph (express bus rate)
\n" ); document.write( "---
\n" ); document.write( "x-7 = 35 mph (local bus rate)
