let time for model T Ford = x
Studebaker = x + 7
Pierce = x + 14
let time for edsel = y
Duesenberg = y - 12
Because the duesenberg came in before the edsel, we can't place the edsel between the Studebaker and pierce because then it would come in fourth but it actually came in third. So it must fall between the ModelT Ford and the Studebaker. Because the Pierce came in fifth, it's time is 22 seconds. Because Duesenberg came in first, it's time is 0.
So the order and times are as follows:
Duesenberg 0 sec
Model T Ford 8 sec
Edsel 12 sec
Studebaker 15 sec
Pierce 22 sec
