When Wicked puts a CyberSquad Seal of Approval on her new "Wickedy Brooms," it's up to Matt, Jackie, Inez and Digit to make sure the brooms are as good as Wicked claims. They try them out, figuring out their speed - how far the different brooms go in a given amount of time. The brooms pass the test - but Wicked doesn't. They must race to Control Central and save Motherboard before Wicked's scheme succeeds! And where's Hacker? And what will he do when he finds out Wicked is trying to take over his turf? EDUCATIONAL OBJECTIVE: You can use speed - the distance you travel in a unit of time - to tell how far you will go in any amount of time.
