Bert is traveling 15 miles per hour slower than Ernie. Bert can travel 150 miles in the same time it takes Ernie to go 225 miles. Find Bert's speed.
\n" ); document.write( "-----
\n" ); document.write( "Ernie DATA:
\n" ); document.write( "distance = 225 miles ; rate = x mph ; time = d/r = 225/x hrs.
\n" ); document.write( "-------
\n" ); document.write( "Bert DATA:
\n" ); document.write( "distance = 150 miles ; rate = x-15 mph ; time = d/r = 150/(x-15) hrs
\n" ); document.write( "----------
\n" ); document.write( "Equation:
\n" ); document.write( "time = time
\n" ); document.write( "225/x = 150/(x-15)
\n" ); document.write( "---
\n" ); document.write( "225x - 225*15 = 150x
\n" ); document.write( "75x = 225*15
\n" ); document.write( "x = (1/5)(225)
\n" ); document.write( "x = 45 mph (Ernie's rate)
\n" ); document.write( "x -15 = 30 mph (Bert's rate)
