Box Lisa has to drive 50 miles to the market.
The market starts at 9 am
She needs to arrive at least half an hour before the market starts.
She leaves home at 7.10 am
Lisa says,
"If I drive at an average of 40 miles per hour I will be there in time."
Is she correct?

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
