In $10$ minutes, through how many degrees does the minute hand of the clock sweep?

In $3$ hours, how many degrees does the hour hand of the clock sweep through?

If the minute hand goes through $180^{\circ}$, how many degrees does the hour hand sweep?

This problem is a great context in which to apply knowledge of angles based on a full turn and it helps to consolidate analogue clock features too.

Having a large geared demonstration clock available would be a good idea to discuss this problem with the group.

Which is the minute hand and which is the hour hand?

How long does it take the hour hand do go a full circle ($360$ $^\circ$) round the clock?

How long does it take the minute hand do go a full circle round the clock?

How many degrees does the minute hand go through in one hour?

So many degrees does it go through in $15$ minutes? In $10$ minutes?

So, how many degrees does it go through in $5$ minutes?

Learners could go on to either of these two problems - Watch the Clock or Two Clocks .
