A bus traveled at an average rate of 50mph and then reduced the average rate to 40mph for the rest of the trip. If the 220 mile trip took 5 hour, determine how long the bus traveled at each rate.
\n" ); document.write( "----
\n" ); document.write( "Faster-leg DATA:
\n" ); document.write( "rate = 50 mph ; time = x hrs ; distance = 50x miles
\n" ); document.write( "----
\n" ); document.write( "Slower-leg DATA:
\n" ); document.write( "rate = 40 mph ; time = 5-x hrs ; distance = 40(5-x) miles
\n" ); document.write( "------
\n" ); document.write( "Equation:
\n" ); document.write( "distance + distance = 220 miles
\n" ); document.write( "50x + 200 - 40x = 220
\n" ); document.write( "10x = 20
\n" ); document.write( "x = 2 hrs
\n" ); document.write( "---
\n" ); document.write( "fast-leg time = 2 hrs
\n" ); document.write( "slow-leg time = 5-2 = 3 hrs.
