Pat won the driving competition. The course was a whole number of miles long and he completed the course in a whole number of minutes (less than two hours). His speed was a two-figure number of miles per hour. The time taken to complete the course was 17 minutes less than the time he would have taken to drive 17 miles less than the distance he would have gone if he had driven for 17 minutes less than the time he would have taken to complete the course at two-thirds of his speed.
How long was the course?
