Kevin investigated the thickness of little ketchup packages from three different fast food restaurants: McDonald’s, Burger King, and Wendy’s. The packages have the same weight and size. He wanted to find out how far each ketchup could run on a tilted plastic board in 10 seconds. At the end of the 10 seconds, he recorded: McDonald’s Brand: 8cm; Burger King: 11 cm and Wendy’s: 13 cm. He did the same experiment three times and the results were all the same.
