If,
29 - 1 = 30
9 - 1 = 10

Upon reaching the finishing mark, they found out that Bobby's car was 1.2 times faster than Wilbur's. Now, Wilbur had reached the mark about 1 minute and 30 seconds later than Bobby. Bobby's car reached the mark of 60 MPH on average.

Can you calculate the distance between the starting mark and the final mark with the help of the given data?

One is to three as three is to five and five is to four and four is the magic number.
What is the pattern?
