Or just look at your speedometer which shows mph and KM per hour.

OK GB. She says ‘let’s run 7 km.’ How many miles is that? Exactly—you can’t because no two fib numbers add up to 7. Not to mention, you somehow are going to try to use this hack backwords? Tell you what, next time she tell yous KM, just pull out your phone or in your head divide 1.6 into it.

Exactly! Maybe a bit easier to multiply by 1.6 instead. This ‘hack’ is silly.

Pretty useless hack. The photo shows ‘25 mph’. Which doesn’t appear in the Fibonacci sequence. Can’t even use this ‘hack’ to convert the number used in photo. And who has the sequence memorized?
