Answer:
The first graph.
Step-by-step explanation:
To start if the graph doesn't start with 10 on the y axis then its wrong due to that when the man boarded the Ferris wheel; leaving you two graphs.
To calculate time it takes to do one complete cycle you do 24/60 = 0.4
** You do this because the x-axis is tenths of a minute **
You then go to the 0.4 mark on the x-axis and compare it with the start of the graph; if the minimum point at 0.4(x-axis) is equal to the 0(x-axis) then you know it made a complete circle.
This is done on the first graph; the other graph makes a complete rotation at 0.8(double the time stated) so it is wrong.
Leaving the first graph your answer.
