The cooling rate of the substance is approximately 0.0732.
According to the statement, the Newton's law of cooling is defined by the following formula:
(1)
Where:
- Final temperature, in degrees Celsius.
- Initial temperature, in degrees Celsius.
- Time, in minutes.
- Cooling rate, in 
.
- Current temperature, in degrees Celsius.
Please notice that substance reaches thermal equilibrium when 
, that is when temperature of the substance is equal to the temperature of surrounding air.
If we know that 
, 
, 
and 
, then the cooling rate of the substance is:
The cooling rate of the substance is approximately 0.0732.

The pythagorean theorem is used to calculate the lengths of a right triangle
The hypotenuse of the triangle is 6.5 cm
<h3>How to determine the hypotenuse of the triangle?</h3>
From the complete question, we have the following side lengths
- Opposite = 5.7 cm
- Adjacent = 3.2 cm
The hypotenuse of the triangle is then calculated as:
Hypotenuse^2 = Opposite^2 + Adjacent^2
This gives
Hypotenuse^2 = 3.2^2 + 5.7^2
Evaluate the sum
Hypotenuse^2 = 42.73
Take the square root of both sides
Hypotenuse = 6.5
Hence, the hypotenuse of the triangle is 6.5 cm
