As expected, our wind racer didn't go that far because of our sail. We didn't want to make it go the furthest but we wanted it to look the best. It was surprising to see that our wind-racer actually went forward on its own, then it had fallen down. Below are our distance, time and speed of our wind-racer.

Distance - 30cm

Time - 2.73s

Speed - 10.1 ms -1
