What is 1 3 of an hour?

One-third of an hour is equivalent to 20 minutes.

In terms of fractions, an hour is divided into 60 equal parts, and one-third of an hour would be one of those 60 parts.

If we consider a clock, one-third of an hour would be a 120-degree angle (since a full circle is 360 degrees).

This duration is commonly used to measure short intervals of time, such as a quick break or a brief phone call. It can also be used to estimate the time it takes to perform simple tasks or activities.
