\n" ); document.write( "--------------------------------------------
\n" ); document.write( "50 mph(1 hr/3600 sec)(5280 ft/1 miles) = 73 1/3 ft/sec
\n" ); document.write( "In 6 seconds the front/back of the bus goes 440 ft
\n" ); document.write( "-------
\n" ); document.write( "The back of the car must clear the front of the bus.
\n" ); document.write( "The back of the car must go 14+28+440 ft = 482 ft in 6 seconds
\n" ); document.write( "-----------------------
\n" ); document.write( "Rate of the Car:
\n" ); document.write( "r = d/t
\n" ); document.write( "rate = (482 ft)/(6 sec) = 80 1/3 ft/sec
\n" ); document.write( "-----------------------
\n" ); document.write( "(241/3 ft/sec)(3600 sec/1 hr)(1 mile/5280 ft) = 54.77 mph.
