The answer is 40 kph. The time is 90 sec. divided by 2 shows speed of 80 kph then divide 80 by2 = 40

The tachymeter bezel and the minute track "switch" places for times greater 60 seconds
Let's use the example from above:
The time reading is 90 seconds.
Next, look up the "90" on the tachymeter bezel. E voilį: the minute track reading is 40 (=40kph/40mph).
If you have a time reading of 3 Minutes (=180 seconds). Check "180" on the bezel... *Bam*: approx. 20kph/20mph.

The reading on the bezel starts to run "backwards" (for time readings greater 60 seconds)... in this way, you are able to measure speeds as slow as 7,5 kph/mph (=500 seconds)

Cheers,
Michael
