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.
your answer would be 6 ways for 1st place 5 ways for 2nd place 4 ways for 3rd place 3 ways for fourth place and in total there are 360 ways in total. (6*5*4*3=360)
