Two people are 3 1/2 miles apart walking towards each other. Their uniform walking differ by 1 mph. They will meet in 1/2 hour. What is the uniform rate of the slower walker? how much of the distance will he/she travel?
\n" ); document.write( "----
\n" ); document.write( "Faster walker DATA:
\n" ); document.write( "rate = r mph ; time = 1/2 hour ; distance = (1/2)r miles
\n" ); document.write( "-----
\n" ); document.write( "Slower walker DATA:
\n" ); document.write( "rate = r-1 mph ; time = 1/2 hour ; distance = (1/2)(r-1) miles
\n" ); document.write( "----
\n" ); document.write( "Equation:
\n" ); document.write( "(1/2)r + (1/2)(r-1) = 7/2
\n" ); document.write( "---
\n" ); document.write( "r + r -1 = 7
\n" ); document.write( "2r = 8
\n" ); document.write( "r = 4 mph
\n" ); document.write( "r-1 = 3 mph (rate of the slower walker.
\n" ); document.write( "distance for slower walker: (1/2)3 = 3/2 miles
