| First, at the very beginning, it should be mentioned that in 1 hour the hand makes a full revolution, which in degree terms has a value of 360o.
Secondly, let’s determine what angle the arrow makes in 6 minutes. Let this angle be xo. Then let’s make the proportion:
60 min – 360o;
6 minutes – xo.
Let us express from the proportion x and calculate it:
x = (360 * 6) / 60 = 360/60 * 6 = 6 * 6 = 36o.
Therefore, in just 3 hours 6 minutes, the arrow will describe the following angle:
a = 360o * 3 + 36o = 1080o + 36o = 1116o.
Answer: 1116o.
