## Solve the task

The robot travels the distance of 90 cm in the time of 6 seconds.

How many seconds does it take for the robot to complete 45 cm at the same speed?

## Extra materials for robotics experiments

- LEGO WeDo 2.0 Milo model with movement sensor (Milo A+B)
- Tablet with internet connection and WeDo 2.0 app
- Measuring tape or a metre long ruler
- Stopwatch

## Extra resources for programming blocks

## 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.

Describe how much did your robot travel:

## 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?

## Look at the solution:

## 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?
