how do I calculate times in seconds and minutes using percentages

Lost for time

I work with equipment that has to run in seconds and minutes at a time and
would like to show the increase in Inq. of 15 % at a time. I have to start
with 35 second and run the increase about 35 times in a day could anyone
help? I am stumped. this has to show on the screen in minutes and seconds.

Seems simple to me, so I might be missing something. Starting at A1 for example,
enter:

A1: 00:00:35 ->format as mm:ss
A2: =A1*1.15

and copy down 34 times.
