\n" ); document.write( "Jessica is walking home from a friend's house. After two minutes she is 1.2 miles from home. Seventeen minutes after leaving, she is 0.7 miles from home. What is her rate in miles per hour? \r
\n" ); document.write( "\n" ); document.write( "Thanks in advance...
\n" ); document.write( "
Let rate be S
\n" ); document.write( "Then we get the following DISTANCE equation: \"matrix%281%2C3%2C+%282%2F60%29+%2A+S+%2B+1.2%2C+%22=%22%2C+%2817%2F60%29+%2A+S+%2B+.7%29\"_______\"%282S%29%2F60+%2B+1.2+=+%2817S%29%2F60+%2B+.7\"
\n" ); document.write( "2S + 72 = 17S + 42 ------- Multiplying by LCD, 60
\n" ); document.write( "2S – 17S = 42 – 72
\n" ); document.write( "– 15S = - 30
\n" ); document.write( "S, or speed = \"highlight_green%28matrix%281%2C4%2C+%28-+30%29%2F%28-+15%29%2C+%22=%22%2C+2%2C+mph%29%29\"
