\n" ); document.write( "30 min = 30/60 = 0.5 hours\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "We'll use rate and time to find the distance.
\n" ); document.write( "distance = rate*time
\n" ); document.write( "distance = (35 mph)*(0.5 hr)
\n" ); document.write( "distance = 17.5 miles\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now use the faster speed to determine how long it would take.
\n" ); document.write( "This assumes you drive the same distance.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "distance = rate*time
\n" ); document.write( "time = distance/rate
\n" ); document.write( "time = (17.5 miles)/(40 mph)
\n" ); document.write( "time = 0.4375
\n" ); document.write( "That's the amount of time in hours.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Multiply by 60 to find its corresponding time in minutes.
\n" ); document.write( "0.4375*60 = 26.25\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Answer: 26.25 minutes
\n" ); document.write( "This is equivalent to 26 minutes + 15 seconds, because 0.25 minutes = 0.25*60 = 15 seconds.
