Answer:
1.5 degrees per second
Step-by-step explanation:
The change in angle is from 3:00 to 7:00, which is a quarter of a full circle. A full circle is 360 degrees, so a quarter circle is 90 degrees.
The change in time is 60 seconds.
So, the angular speed would be:
1.5 degrees per second.
Hope this helps!
