 In addition, production cars are beginning to have some success. The team boss is keen to maintain the competitive spirit by publishing a ranking of the production cars.
 
-## 1. Enable cars to be driven on the same test track
+## 1. Implement the Interface
 
-Please add a method to the `RemoteControlCar` interface to encapsulate the behavior of `drive()` for the two types of car.
+Please add two methods to the `RemoteControlCar` interface:
+- `drive()`, returning nothing, and
+- `getDistanceTravelled()`, returning an `int`.
 
-```java
-TestTrack.race(new ProductionRemoteControlCar());
-TestTrack.race(new ExperimentalRemoteControlCar());
-// this should execute without an exception being thrown
-```
+Then make `ProductionRemoteControlCar` and `ExperimentalRemoteControlCar` implement the `RemoteControlCar` interface.
+This includes implementing all methods required by the interface. 
+
+## 2. Drive.
 
-## 2. Enable the distance travelled by different models on the test track to be compared
+Each call of `.drive()` should make the car travel a certain distance:
+- a `ProductionRemoteControlCar` drives 10 units,
+- an `ExperimentalRemoteControlCar` drives 20 units.
 
-Please add a method to the `RemoteControlCar` interface to encapsulate the behavior of the `getDistanceTravelled()` method for the two types of car. Notice that the Experimental model has a different speed than the Production model. 
+The `.getDistanceTravelled()` method should return the number of units that the car has travelled in its lifetime.
 
 ```java
 ProductionRemoteControlCar prod = new ProductionRemoteControlCar();
-TestTrack.race(prod);
-ExperimentalRemoteControlCar exp = new ExperimentalRemoteControlCar();
-TestTrack.race(exp);
+prod.drive();
 prod.getDistanceTravelled();
 // => 10
+        
+ExperimentalRemoteControlCar exp = new ExperimentalRemoteControlCar();
+exp.drive();
 exp.getDistanceTravelled();
 // => 20
 ```
 
-## 3. Allow the production cars to be ranked
+## 3. Race!
+
+Implement the `TestTrack.race(RemoteControlCar car)` method in which the `car`s get to `drive()`.
+```java
+TestTrack.race(new ProductionRemoteControlCar());
+TestTrack.race(new ExperimentalRemoteControlCar());
+// this should execute without an exception being thrown
+```
+
+## 4. Allow the production cars to be sorted
 
-Please implement the `Comparable<T>` interface in the `ProductionRemoteControlCar` class. The default sort order for cars should be ascending order of victories.
+Please implement the `Comparable<T>` interface in the `ProductionRemoteControlCar` class.
+The default sort order for cars should be descending order of victories.
 
-Implement the static `TestTrack.getRankedCars()` to return the cars passed in, sorted in ascending order of number of victories.
+Implement the static `TestTrack.getRankedCars()` to return the cars passed in, sorted in descending order of number of victories.

 prc1.setNumberOfVictories(3);
 prc2.setNumberOfVictories(2);
-int rankings = TestTrack.getRankedCars(prc1, prc2);
-// => rankings[1] == prc1
