Challenge: Inheritance Check

Problem statement #

This challenge gives you an idea of how to use the instanceof variable. You can use it in checking for inheritance between classes.

You are given some code written by a student. The student was asked to implement inheritance by creating a Vehicle class (containing the defined properties speed and model) and a Car class, which inherits these properties from the Vehicle class. However, as you can see, the student cheated and copy and pasted the Vehicle class constructor.
