average speed = $\"+total+distance+%2F+total+time+\"$
\n" ); document.write( "total time = 1 hr +2 hr = 3 hrs
\n" ); document.write( " distance traveled in first 1 hr = speed * time
\n" ); document.write( " =10*1
\n" ); document.write( " =10 miles
\n" ); document.write( "distance traveled in next 2 hrs = 25*2
\n" ); document.write( " =50 miles
\n" ); document.write( "total distance = 10+50 = 60 miles
\n" ); document.write( " average speed = $\"+60%2F3\"$
\n" ); document.write( " = 20 miles /hr
\n" ); document.write( " Result : Average speed = 20 miles /hr
\n" ); document.write( " \n" ); document.write( "
