A man walks at a pace of 3 miles per hour. After 2 hours he stops for a rest. Let t be time AFTER the rest. Let d be the TOTAL distance traveled since he started. Write an equation linking d and t. Explain what you did to get your answer.
\n" ); document.write( ":
\n" ); document.write( "The dist walked before his rest: 2 hrs at 3 mph
\n" ); document.write( "2*3 = 6 mi before the rest
\n" ); document.write( ":
\n" ); document.write( "The dist walked after the rest: t hrs at 3 mph
\n" ); document.write( "3t = dist after the rest
\n" ); document.write( ":
\n" ); document.write( "Total dist = dist after rest plus dist before rest
\n" ); document.write( "d = 3t + 6 \n" ); document.write( "
