- You have to [explicitly return an integer][return] from a method.
- The method's parameter is an [integer][integers].
- You can use the [mathematical operator for subtraction][operators] to subtract values.

## 3. Calculate the preparation time in minutes

- You need to define a [method][methods] with a single parameter.
- You have to [explicitly return an integer][return] from a method.
- The method's parameter is an [integer][integers].
- You can use the [mathematical operator for multiplicaton][operators] to multiply values.

## 4. Calculate the elapsed time in minutes
