Question 18
A child is operating a remote-controlled car on a flat surface. Starting from the child’s feet, the car moves forward 1 metre, makes a $30^\circ$ turn counterclockwise, moves forward 1 metre, makes a $30^\circ$ turn counterclockwise, and so on. When the car first time returns to its starting point for the first time, what is the total distance, in metres, that it has covered?
