Finding b/min of a track

I have 2 tracks recorded. The first Mono was the “Click” track.

Now forgot what speed.

How is easiest to find what that track is as “Beats per minute/recorded”?

What Tools etc?
Thank you.

Select 1 minute of the click track, and count the number of clicks.
If the tempo was a nice “round” number like 120 bpm, then you can save time and effort by counting the number of beats in 10 seconds and multiplying by 6 (6 lots of 10 seconds in 1 minute)
