Husband and wife start from the same starting point and run in the same direction. The husband runs twice the rate of the wife. After 1 1/2 hours, the distance between the two is 7.5 km. find the speed of each.\r
\n" ); document.write( "\n" ); document.write( "----------
\n" ); document.write( "Wife DATA:
\n" ); document.write( "rate = x kph ; time = 1.5 hours ; distance = rt = 1.5x km
\n" ); document.write( "---------
\n" ); document.write( "Husband DATA:
\n" ); document.write( "rate = 2x kph ; time = 1.5 hours; distance = rt = 3x km
\n" ); document.write( "--------
\n" ); document.write( "EQUATION:
\n" ); document.write( "distance - distance = 7.5 km
\n" ); document.write( "3x - 1.5x = 4.5 km
\n" ); document.write( "1.5x = 7.5
\n" ); document.write( "x= 5 kph ( wife's rate)
\n" ); document.write( "2x = 10 kph (husband's rate)
\n" ); document.write( "--------
