\n" ); document.write( "Mary and Murray travel respectively at x and y km/h heading directly towards each other across a distance of 960 km. If both start at 10 am they will meet at 3 pm. If Murray starts at 6 am and Mary starts at 10 am they will meet at noon. Find (x,y)
\n" ); document.write( "
5x + 5y = 960____5(x + y) = 5(192)______x + y = 192 ------- eq (i)
\n" ); document.write( "2x + 6y = 960____2(x + 3y) = 2(480)_____x + 3y = 480 ------ eq (ii)
\n" ); document.write( "2y = 288 ------- Subtracting eq (i) from eq (ii)
\n" ); document.write( "
