James can hike three miles per hours faster on level ground than he can on uphill terrain. Yesterday, he hiked a total distance of 32 miles and spent 2 hours on level ground and 5 hours on uphill terrain. What is the rate of his speed on level ground?
\n" ); document.write( ":
\n" ); document.write( "Let s = walking speed on level ground
\n" ); document.write( "then
\n" ); document.write( "(s-3) = speed uphill
\n" ); document.write( ":
\n" ); document.write( "Write a distance equation Dist = time * speed
\n" ); document.write( "2s + 5(s-3) = 32
\n" ); document.write( ":
\n" ); document.write( "2s + 5s - 15 = 32
\n" ); document.write( ":
\n" ); document.write( "7s = 32 + 15
\n" ); document.write( ":
\n" ); document.write( "7s = 47
\n" ); document.write( "s = \"47%2F7\"
\n" ); document.write( "s = 6.714 mph on level ground
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution: speed uphill = 3.714:
\n" ); document.write( "2(6.714) + 5(3.714) =
\n" ); document.write( "13.43 + 18.57 = 32 mi \n" ); document.write( "
