I’m not sure if your asking for the solution, but Hope this helps!
The values for y are as follows
4.5, 4, 3.5, 3, 2.5, 2
The answer #6 is j. 100. He uses the treadmill for 40% so that means 60% of his exercise is not on the treadmill.
40%= 40 mins
60%= 60 mins
total: 100%= 100 mins.
Hope this helps!
The answer is 6 you just divide
