She would really have to be flying to pass that truck in
only 6 seconds.

First we must change 50 mi/h to ft/s.



replace  by 
replace  by 



replace  by 







So in 6 seconds, using ,
the truck travels



We start with the front bumper of the car even
with the tailgate of the truck.

So in that 6 seconds, the front bumper of the 
car must travel:

1. the 440 feet which the truck travels in 6 seconds.
2. the 30 feet from the tailgate of the
   truck to the front bumper of the truck.
3. the 14 feet to get the back bumper of
   the car even with the front bumper of the
   truck.

That's a total of feet, which she
must travel in 6 second.  

Now we find her rate using 






Now we must get that to :

Multiply by 

×

Multiply by 

××

Multiply by 

×××

Cancel the , the , and the :

×××



That's fast!!!  I don't she'll do it, do you?
