Final answer:
The radius of Ashley's trundle wheel is approximately 666.7 cm.
Step-by-step explanation:
To find the radius of the trundle wheel, we can set up a proportion. We know that the wheel needs to go around 3 times for every 2000 cm it is pushed. We can set up the proportion:
3 rotations / 2000 cm = 1 rotation / x cm
Cross multiplying, we get:
3x = 2000
Dividing both sides by 3, we get:
x = 666.7 cm
Therefore, the radius of Ashley's trundle wheel is approximately 666.7 cm.
