Help with a constant acceleration problem?

A smaller propeller airplane can comfortably achieve a high enough speed to take off on a runway that is 1/4 mile long. A large, fully loaded passenger jet has about the same acceleration from rest, but needs to achieve twice the speed to take off. What is the minimum runway length that will serve?

Hint: you can solve this problem using ratios without having any additional information.

If you could solve and show your steps with ratios it'd be much appreciated.
