ET50 / Photosynthesis SAC

Hey!! So I had my photosynthesis SAC about 2 days ago, and there was a question about finding 1/ET50 and I don't quite understand what it means (still don't :-\) so any help would be appreciated, thanks!!

I did a quick google search and realsied I too did that prac when I did 3/4 biology.

I found that the time required for 50% of the leaf disks to float is represented as Effective Time = ET50
So I would assume 1/ET50 is the reciprocal of that.

Along with what Sine said and you have to make sure your answer is in a fraction form with no decimals, if needed you can use a scientific calculator to convert the fraction and those who haven't done a photosynthesis sac yet, don't bother connecting the lines for the graph if you have to draw one up

Example:
et50= 9.5 minutes
=1/9.5
=2/19
