36sec ---> 600m.
9sec ------> 600 * 9/36 = 150meters.
9sec ------> 600 * 9/36 = 150meters.

1km = 1000 meters.
1 hour = 3600 sec.
So, 1000/3600 = 5/18.
1 hour = 3600 sec.
So, 1000/3600 = 5/18.

Length= Speed * Time.
Length = 60*(5/18)*9,
Length = 150m.
Length = 60*(5/18)*9,
Length = 150m.

60min -> 60km.
1min ->1km.
10sec ->166.
So, 9sec -> 149.5.
1min ->1km.
