The truck had a 15 minutes head start and was going 60mph. That is a mile per minute. So 15 minutes later the car eters the road exactly 15 miles behind the truck.\r
\n" ); document.write( "\n" ); document.write( "The car is going 8mph faster than the truck. So how much time does it take to go 15 miles at 8 mph?\r
\n" ); document.write( "\n" ); document.write( " $\"distance+=+speed+%2A+time\"$
\n" ); document.write( " $\"15+=+8+%2A+timeInHours\"$
\n" ); document.write( " $\"15%2F8+=+timeInHours\"$
\n" ); document.write( "1.875 hours or 1:52 minutes 30 seconds \n" ); document.write( "
