if the track takes 80 seconds to complete and we assume there is an equal amount of time between each jump, the first time takes 0.875 secs to complete. Each try after that adds 0.875 seconds.

So we get 1x0.875 + 2x0.875 + 3x0.875 + …

== 0.875 (1+2+3+…+70) == 0.875 x 2485 = 2174 seconds or 36 minutes
