\n" ); document.write( "a car and a bus start at 8:00 a.m. from the same point and travel in the same direction. the average speed of the car is 60 mph.
\n" ); document.write( "in 2 hours the car is 30 miles ahead of the bus. find the average speed of the bus.
\n" ); document.write( "~~~~~~~~~~~~~~~~~~~~~\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "

\r\n" );
document.write( "Since the average speed of the car was 60 mph (given !), in 2 hours it covered  2*60 = 120 miles.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Since the car was  30 miles ahead the bus at that time moment,\r\n" );
document.write( "\r\n" );
document.write( "it means that the bus covered  90 = 120 - 30 miles in 2 hours.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Hence, the average speed of the bus was   = 45 miles per hour.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Answer.  The average speed of the bus was  45 mph.\r\n" );
