The Morena family drove to Yosemite National park in 3 hours 24 minutes.
\n" ); document.write( "On the way home, they averaged 5 miles per hour less and the trip took 3 hours 42 minutes.
\n" ); document.write( " How far from Yosemite National park do they live?
\n" ); document.write( ":
\n" ); document.write( "Convert 3 hr 24 min to 3.4 hrs
\n" ); document.write( "Convert 3 hr 42 min to 3.7 hrs
\n" ); document.write( ":
\n" ); document.write( "Find the speed first
\n" ); document.write( ":
\n" ); document.write( "Let s = return speed
\n" ); document.write( "then
\n" ); document.write( "(s+5) = to park speed
\n" ); document.write( ":
\n" ); document.write( "Write a dist equation, dist = speed * time
\n" ); document.write( ":
\n" ); document.write( "back dist = out dist
\n" ); document.write( "3.7s = 3.4(s+5)
\n" ); document.write( "3.7s = 3.4s + 17
\n" ); document.write( "3.7s - 3.4s = 17
\n" ); document.write( ".3s = 17
\n" ); document.write( "s = \"17%2F.3\"
\n" ); document.write( "s = 56.67 mph back from the park
\n" ); document.write( "and
\n" ); document.write( "61.67 mph to the park
\n" ); document.write( ":
\n" ); document.write( "Find the dist
\n" ); document.write( "3.7 * 56.67 = 209.67 mi dist to the park
\n" ); document.write( "Confirm the dist
\n" ); document.write( "3.4 * 61.67 = 209.67 mi \n" ); document.write( "
\n" );
