'Decimal Clock' printed from https://nrich.maths.org/
In the late 18th century, a decimal clock was proposed, in which there were 100 'minutes' in one 'hour' and 10 'hours' in one day.
Assuming that such a clock started from 0:00 at midnight, what time would it show when an ordinary clock showed 6am?
