Procedures with parameters

Kash is writing code to calculate formulas from his physics class. He's currently working on a procedure to calculate average speed, based on this formula:

Average speed = \frac{Total Distance}{Total Time}

Which of these is the best procedure for calculating and displaying average speed?

🤔

This code is written in pseudocode. You can't actually run pseudocode, but we use it for planning programs and for thinking about code independently of specific programming language.

AP CSP exam questions use pseudocode, so it's helpful to become familiar with it.

Here is a reference for the pseudocode used here:

PROCEDURE name (parameter1, parameter2, ...)
{
     <instructions>
}

A procedure called "name" that takes zero or more parameters. The procedure contains programming instructions.

a ← expression

Evaluates expression and assigns the result to the variable a.

DISPLAY (expression)

Displays the value of expression, followed by a space.

**Arithmetic operators**
Instruction	Explanation
`a + b`	Evaluates to the result of `b` added to `a`
`a - b`	Evaluates to the result of `b` subtracted from `a`
`a * b`	Evaluates to the result of `a` multiplied by `b`
`a / b`	Evaluates to the result of `a` divided by `b`
