Round problem

Wouldn't this return a DivideByZero exception during a vertical line?

Solved :)

I have exactly the same problem as listed above. Sample Tests sometimes they pass, sometimes I get this message:

Test FailedExpected: Triangle
But was: Rectangle

Random tests always fail but on different shapes. Can you point out what the problem was.

I got stuck on AverageConsumptionsAfterBraking i can't figure out how this test

var car = new Car();

    car.EngineStart();

    car.Accelerate(30);
    car.Accelerate(30);
    car.Accelerate(30);

    car.BrakeBy(10);
    car.BrakeBy(10);
    car.BrakeBy(10);

gives 0,0009 l/s average consumption by time? For me it should be (0.002 * 3)/7 = 0,00086

Could you help me with that?
