<div style="font-family: 'Times New Roman'; font-size: 16px;">Hello, I try to make a car with Racket. So far I have got this : (define (rechthoek a) (rectangle 200 50 "solid" "black")) (define (cirkel a) (circle 20 "solid" "red")) (define (auto a) (overlay/xy (rechthoek a) -50 30 (cirkel a))) (auto 1) As far as I can see I cannot use overlay/xy to make the second wheel. Must I make a images of the 2 wheels first and use overlay/xy or is there another way to achieve this ? Regards, Roelof Wobben </div>
