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?

2:50

Step-by-step explanation:

On an ordinary clock, there are 24 hours.

1)  6/24 = 0.25   (The percentage in which the day has passed)

2) 10 (total hours in a day in the decimal clock) * x 0.25 = 2.50

3) 2.5 Hours. On a typical clock, that would read 2:30, however, because the decimal clock proposes that there are 100 minutes in one hour, it will be 2:50, Therefore, the clock will display 2:50
