EXPERIMENT 1
Make the robot drive from a certain starting point for 6 seconds at speed 1. Measure, how long of a distance the robot travels. Now make the robot drive forward from the same spot for 3 seconds. Measure again, how long of a distance the robot travels.

EXPERIMENT 2
Mark a distance of 20 cm. Use a stopwatch to measure, how fast the robot travels this distance at speed 3. Guess, how fast would the robot travel 40 cm. Experiment.
How fast did your robot travel the distances?

Example of the solution
EXPERIMENT 3
Set the speed of the robot to 2 times higher than 5. How long of a distance does the robot travel in 2 seconds? Decrease the speed of the robot 2 times. How long of a distance does the robot travel now in 2 seconds?
