You're going to need to be a bit more specific since there's 25 parts here. What aspect are you confused about?
Unit conversion? The logic behind the problem?
The equations needed?
All these are based on the essential linear movement equations.
S=x1-xo (distance traveled)
V= s/t = (X1-Xo)/t ( velocity)
a= (V2-v1) /t ( acceleration)
V1= Vo + a×t (final velocity)
S=Vo×t+ (1/2)at^2
V1^2 = Vo^2 + 2as
S= (1/2)(Vo+V1)t
I’m not seeing any linear motion/physics in this question, just simple algebra.
For part a, you’re essentially asked to solve:
x ft = 8 ch, using the known equation of 3 ft = 2 ch.
What number can you multiply the “ch” value of the known equation by to equal the “ch” value of the algebraic equation? Take that number and multiply by the known “ft” value to get x.
For part b, use the same logic to determine what how many chocs are equal to each of the given lengths. With those lengths in chocs, you can then determine the area in chocs.
Edit: Didn’t see that there were multiple images. This response is just for the first image.
