How would I calculate the blink rate? Thanks.

Number of blinks / time

As it asks you to count blinks per 20 seconds, you must do the number of blinks in that 20 seconds divided by 0.3 (as 3 x 20 = 60, or 1 minute)
then multiply the answer by 3! hope that helps :smile:

As it says do the test twice, meaning that you've got 2 sets of results over 20 seconds, do you do the same thing but extrapolate from 40 to 60 rather than 20 to 60?

Example:

First test: 10 blinks in 20 seconds
Second test: 20 blinks in 20 seconds

Which means you've got 30 blinks in 40 seconds (and dividing by 2 gives you 15 in 20 seconds), add them together which gives you 45 blinks/minute? Would this be the right method? Thank you!

Yeah I'm pretty sure that's correct! No problem :smile:
