A ship traveled at an average rate of 25 miles per hour going west.
\n" ); document.write( " It then traveled at an average rate of 19 miles per hour heading north.
\n" ); document.write( " If the ship traveled a total of 145 miles in 7 hours, how many miles were traveled heading west?
\n" ); document.write( ":
\n" ); document.write( "Find how long the ship traveled at each speed
\n" ); document.write( "let w = time heading west at 25 mph
\n" ); document.write( "the total time is 7 hrs, therefore
\n" ); document.write( "(7-w) = time heading north at 19 mph
\n" ); document.write( ":
\n" ); document.write( "A distance equation; dist = speed * time
\n" ); document.write( "25w + 19(7-w) = 145
\n" ); document.write( "25w + 133 - 19w = 145
\n" ); document.write( "25w - 19w = 145 - 133
\n" ); document.write( "6w = 12
\n" ); document.write( "w = 12/6
\n" ); document.write( "w = 2 hrs traveling west
\n" ); document.write( "therefore
\n" ); document.write( "2 * 25 = mile going west
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Confirm this solution, 7 - 2 = 5 hrs going north
\n" ); document.write( "19 * 5 = 95mi
\n" ); document.write( "25 * 2 = 50mi
\n" ); document.write( "--------------
\n" ); document.write( "total dist 145 mi \n" ); document.write( "
\n" );
