Creating a static formula class
In our scenario, we have a Formula class with methods for mathematical formulas that can be useful to many developers using our code. You will add a formula to calculate the speed that will be available for use, thereby ensuring developers using your code do not need to write code for the same speed calculation, saving precious time.

Instruções do exercício
- Make the
Formulaclass astaticclass. - Create a
staticcalculateSpeedmethod that returns adoubleand takes twodoubleparameters,distanceandtime. - The
calculateSpeedmethod should return the division operation result ofdistancedivided bytime. - Inside the
mainmethod, call thecalculateSpeedmethod of theFormulaclass, without creating an instance and print the operation result with thedistanceparameter set to165.00and thetimeparameter set to15.00.
