one lap at the indianapolis speedway is 2.5 mi.
\n" ); document.write( " in a race, a car stalls and then starts 30.0 s after a second car.
\n" ); document.write( " the first car travels at 260 ft/s, and the second car travels at 240 ft/s.
\n" ); document.write( " how long does it take the first car to overtake the second,
\n" ); document.write( ":
\n" ); document.write( "find how far Car 2 will be from Car 1, in 30 sec
\n" ); document.write( "30 * 240 = 7200 ft
\n" ); document.write( ":
\n" ); document.write( "Let t = time for Car 1 to overtake Car 2
\n" ); document.write( ":
\n" ); document.write( "Write a distance equation:
\n" ); document.write( ":
\n" ); document.write( "Car 1 dist = Car 2 dist + 7200 ft
\n" ); document.write( "260t = 240t + 7200
\n" ); document.write( "260t - 240t = 7200
\n" ); document.write( "20t = 7200
\n" ); document.write( "t = \"7200%2F20\"
\n" ); document.write( "t = 360 seconds (6 minutes) for car 1 to catch car 2
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "\"and which car will be ahead after eight laps\"
\n" ); document.write( ":
\n" ); document.write( "Find which lap they are on when car 1 overtakes car 2
\n" ); document.write( ":
\n" ); document.write( "Using car 2 distance. Car 2 travel time 360 + 30 = 390 sec
\n" ); document.write( "\"%28390%2A240%29%2F%282.5%2A5280%29\" ~ 7th lap
\n" ); document.write( "We can confirm this with car 1's travel of 360 sec
\n" ); document.write( "\"%28360%2A260%29%2F%282.5%2A5280%29\" ~ 7th lap also
\n" ); document.write( ":
\n" ); document.write( "Obviously, by the 8th lap Car 1 will have passed Car 2.
\n" ); document.write( "
\n" );
