How do I find the speed?

The problem says "The engine sprocket of Kyle’s go-cart is 4 cm indiameter. It’s attatched to a 20-cm rear axel sprocket that drives the go-cart." Part a says "Find the angular velocity of the rear axle when the engine is turning 4200 rpm" I understand part a, but part b says "Find the speed of the go-cart in km/hr under the conditions stated in part a if the rear wheels are 35 cm in diameter." Aaaahh, I’m confused. Thanks!
Okay, I’m not asking for somebody else to do it for me, but for somebody to explain it to me. What’s wrong with asking for help?
Thanks to the people who helped, though. Sorry.

It may go like this …
4 / 20 = 1/5
4200 * 1/5 = 840 rpm at the rear axel
840*35=29400cm per minute
0.294 Km per minute
0.294 * 60 = 17.64 Km/h
