I can't understand what you wanted with the second question (or if that is even a question), but the answer to the first one is 42.

I'm sorry, but this isn't clear. Maybe remake the layout you wrote? Because 3 3 4 doesn't make sense.
You will have to add 190 with 95 and that will be 285 because he rides 190 miles in FOUR days and you will need to know the half of 190 to get 2 days because each day he would ride 47.5 miles each day and 47.5+47.5=95.
The Answer is 285.
