I had to do a Lab project. It was letting a cart go down a piece of wood with tape at 30cm, 60cm, 90cm and 120cm. The time was ---30cm----.94 60cm--1.19
90cm---1.49 and 120cm----1.81 Question is based on your data, does it take roughly twice as long to go twice the distance (look at first and second distances) with accelerated motion?
