Question

The hands of a clock suggest an angle whose measure is continually changing. How many degrees does a minute hand move through during 4 ​-minute time​ interval?
In 4 ​-minute time interval a minute hand moves __ degrees.

Answer 1

Step-by-step explanation:

oh, come one ! you can literally see that one ...

a full rotation on a clock is a full circle and stands therefore for 360°.

for the minute hand these 360° represent 60 minutes.

4 minutes of 60 is a fraction, a ratio, and the same ratio applies then also to 360°.

4/60 = 1/15

360 × 1/15 = 24°

so, 4 minutes represent 24°.
