The first technique one could use in estimating the total number of seconds spent for five sprints Oni made are these:

1. Add everything up and you will get the total seconds which is 60.90 seconds all in all.

2. Do the first method and divide the sum with 60 (seconds) in order to get the minutes and the remainder will be the seconds, as in writing or reading the time. 60.90 divided by 60 is 1min and 0.9 seconds.
