The speed of an angry goblin is equal to 8 miles per hour, if it flies 32 miles in 4 hours.

Given the following data:

Distance = 32 miles. Time = 4 hours.

To determine the speed of an angry goblin:

Speed can be defined as the distance covered by an object per unit time and it is usually measured in meter per seconds (m/s).

Also, speed has magnitude but no direction and as such it is a scalar quantity.

Mathematically, speed is given by the formula;

[tex]Speed = \frac{distance}{time}[/tex]

Substituting the given parameters into the formula, we have;

[tex]Speed = \frac{32}{4}[/tex]

Speed = 8 mi/hr.

Therefore, the speed of an angry goblin is equal to 8 miles per hour, if it flies 32 miles in 4 hours.
