Algebra.Com's Answer #811547 by htmentor(1343)![]() ![]() You can put this solution on YOUR website! Let h = Harry's speed, and j = John's speed \n" ); document.write( "Then their relative speed, traveling toward each other is h + j \n" ); document.write( "Since they travel 90 km in 2 h, we can equate their relative speed to 90/2 [km/h] \n" ); document.write( "Since, j = 2h, we have \n" ); document.write( "3h = 45 -> h = 15 km/h \n" ); document.write( "Thus Harry's speed is 15 km/h and John's is 30 km/h \n" ); document.write( " |
