Solution
Let’s imagine that the entire watch face is divided into 4 parts, 15 minutes each part. Let me remind you that when determining the values ​​of trigonometric, they also use a circle divided by 4 quarters.
Respectively
1 quarter is located in the range from 15 minutes to 0
Quarter 2 is located between 0 and 45 minutes
Quarter 3 is located within 45 minutes to 30 minutes
4th quarter is located in the range from 30 minutes to 15 minutes
Now let’s give the dependencies
an interval of 15 minutes is equal to 90 degrees
hence we can write the following
15min = 90grad
Divide both parts by 15 and get the number of degrees per minute
1min = 6degrees
Now let’s calculate for 8 minutes
To do this, multiply both sides by 8 and get
8min = 48degree
Answer 8 minutes corresponds to 48 degrees
