Algebra.Com's Answer #445407 by Lisalovemath(2)![]() ![]() ![]() You can put this solution on YOUR website! First, add both rates of the runners \n" ); document.write( "80+90=170 \n" ); document.write( "Then, count the number of rates(this number is very important for the next step). \n" ); document.write( "There are 2. \n" ); document.write( "Now, divide 170 by 2. Dividing the combined rates (170) by the total numbers of rates(2), we will find the average. \n" ); document.write( "170/2=85 kilos per hour. \n" ); document.write( "Thus, the average kph is 85 kph. \n" ); document.write( " |
