Question

A marble begins a marble track at 18.5 inches above the tabletop. It goes down a slide 8 inches long, rides up two paddle wheels that are 2 1/4 inches each. You want to split the remaining height into three equal sections, how long will each section be?

Answer 1

2in

Explanation:

18.5in - 8in = 10.5in

10.5in - (2.25in * 2) = 10.5in - 4.5in = 6in

6in / 3 = 2in
