Then calculate how far each wheel has traveled after one complete circuit around the circle.
There are 32 humps in the track.Use this approximate information for wheel sizes:
| Small Tricycle | Large Tricycle |
| wheel 1 side length = 8 in. | wheel 1 side length = 15 in. |
| wheel 2 side length = 10 in. | wheel 2 side length = 13 in. |
| wheel 3 side length = 6 in. | wheel 3 side length = 18 in. |
