Process:
1. Display welcome screen
2. Prompt for worm’s length
3. Prompt for the beginning distance between the worm and the apple. 4. Calculate the distance between the worm and the apple by the worm’s length till the worm can enter the apple.

Input
Worm’s Length (real: wormsLength)
Beginning Distance (real: startDistance)
Output
Incremental distance between the worm and apple Distance (real)

Main Module
Begin Main Module:
Declare startDistance as real
Declare wormLength as real
Write, “The journey begins.”
Call User Input Module
Call Distance to apple calculations Module
End Main Module

User Input Module
Begin User Input Module
Write, “How long is this worm?”
Input wormLength

Write, “How far away is the worm from the apple?”
Input startDistance

End User Input Module

If (wormLength > 0 And startDistance > 0)
Then
While (startDistance > 0) Set Distance = startDistance – wormLength End While
End Then
End If
Write, “Good job the worm made it to the apple!”
