12+4x^2+3x^3-2x is the answer.
The circumference of a Ferris wheel:
C = 2 r π
C = 2 · 70 · 3.14
C = 439.6 ft
439.6 : 40 = 10.99 ≈ 11 ft
Answer:
The cars are placed approximately 11 ft apart.
The main formula we use here is Work=Rate*Time,
1. The rate (speed of working) of Dominik is

2. Let the the rate of Katarina be

Together they have a rate of

equal to

(project per hour)
so

simplify the units:



so the rate of Katarina is 3/40 (proj per hour)
Now, the rate of Dominik was 1/8 (pr/hr)=5/40 (pr/hr)
In 5 hours Dominik complets 5*5/40=25/40 of the project
Katarina completes 5*3/40=15/40 of the project.
