Rate times time = distance
\n" ); document.write( "let R = rate in miles per hour.
\n" ); document.write( "let T = time in hours.
\n" ); document.write( "let D = distance in miles.
\n" ); document.write( "-----
\n" ); document.write( "let R = 3 miles per hour.
\n" ); document.write( "-----
\n" ); document.write( "start with D = R * T
\n" ); document.write( "divide both sides of the equation by R
\n" ); document.write( "equation becomes:
\n" ); document.write( "D/R = T
\n" ); document.write( "which is the same as:
\n" ); document.write( "T = D / R
\n" ); document.write( "-----
\n" ); document.write( "equation we want to work with is: T = D / R
\n" ); document.write( "since R = 3, equation becomes:
\n" ); document.write( "T = D / 3
\n" ); document.write( "if we let D = n, equation becomes:
\n" ); document.write( "T = n / 3
\n" ); document.write( "since T = number of hours it takes for hiker to get there, equation becomes:
\n" ); document.write( "number of hours it takes for hiker to get there = n / 3
\n" ); document.write( "-----
\n" ); document.write( "answer is:
\n" ); document.write( "number of hours it takes for hiker to walk n miles is n / 3 hours.
\n" ); document.write( "-----
\n" ); document.write( "example:
\n" ); document.write( "let n = 300 miles
\n" ); document.write( "if the hiker is traveling at 3 miles per hour, it will take 300 / 3 = 100 hours to get there
\n" ); document.write( "-----\r
