Simple physics, Velocity(Speed)=Distance traveled / Time taken
so measure a set distance down your incline and time the toy rolling down if you want a true speed make sure the toy is going at full speed before it crosses the start line and you start your timer, otherwise you will get an average including the toys acceleration time and as such won't be a true representation

What equipment was needed for this experiment
Always perform the experiment under adult supervision.
Depending on the size/importance of the experiment, they can either simply repeat as normal or if needed gather more resources for the experiments. Scientists always perform experiments at least three times, to make sure nothing is abnormal in an experiment.
This an experiment you may perform simply for yourself. Hold a steel needle so that its tip is in the flame of a candle.

only when he wanted to perform an experiment.
To prove or disprove a theory. If you didn't perform experiments you wouldn't have the evidence to move forward in your scientific knowledge. Try an experiment 4 times to get a reliable average result.

The scientific method
in designing your experiment which step did you perform first?
i dont no but i need the anwser Yes an experiment will test a theory. You perform an experiment to test the hypothesis. If the experiment can be repeated then the hypothesis becomes a theory. People perform experiments to test and retest theories.
we need to identify the precautions method in performing an experiment inside the laboratory to determine do's and don'ts and to make our experiment satisfied. Knowing the laboratory set-up is important so that we can perform our experiments easy and enjoyable.
