If I can drive 630 miles in 10.5 hours, how many miles can I drive in 4 hours?
\n" ); document.write( ":
\n" ); document.write( "You can use a simple ratio equation, let d = dist in 4 hr
\n" ); document.write( "\"d%2F630\"=\"4%2F10.5\"
\n" ); document.write( "Cross multiply
\n" ); document.write( "10.5d = 630 * 4
\n" ); document.write( "10.5d - 2530
\n" ); document.write( "d = \"2520%2F10.5\"
\n" ); document.write( "d = 240 miles
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "You can confirm this by finding the speed
\n" ); document.write( "\"630%2F10.5\" = 60
\n" ); document.write( " 60 * 4 = 240 mi
