What angle (in degrees) does the minute hand describe in 18 minutes?

To solve this problem, we introduce the conditional variable “X”, through which we denote the angle in degrees, which the minute hand describes in 18 minutes.

Let’s take into account the fact that in 60 minutes the minute hand describes an angle of 360 degrees.

Then, based on the data of the problem, we will compose the following proportion: 360 degrees are related to 60 minutes, as X degrees are related to 18 minutes.

Then, based on this proportion, we will compose the following equation: X x 60 = 360 x 18.

Solving this equation, we get X equal to 108 degrees.

Answer: 108 degrees.
