    Answer: The answer is 80 mph.

    Step-by-step explanation: 1. Divide 14 from 571.

    2. You'll get the answer 40. So it's 40 mph.

    3. If she's trying to shorten by 1/2 then she should drive 80 mph because if you drive 80 mph it will take 7 hours instead of 14 hours. (She'll go 7 hours because you divide 14 hours by 2. Then you have to multiply 2 to 40.)
