\n" ); document.write( "A man travels 40 mph to his friends house. When he goes back on the same route he travels 45 mph. It was a four hour round-trip. How far did he travel
\n" ); document.write( "
Let distance, one-way, be D
\n" ); document.write( "Then time taken to travel on 1st trip: \"D%2F40\"
\n" ); document.write( "Time taken to travel on 2nd trip: \"D%2F45\"
\n" ); document.write( "Since round-trip took 4 hours, then we can say that:
\n" ); document.write( "\"D%2F40+%2B+D%2F45+=+4\"
\n" ); document.write( "\"9D+%2B+8D+=+1440\" -------- Multiplying by LCD, 360
\n" ); document.write( "17D = 1,440
\n" ); document.write( "D, or distance = \"1440%2F17\", or \"highlight_green%2884%2612%2F17%29\" miles \n" ); document.write( "
\n" );
