Then describe what is happening here.
Comparisons - $500
ANSWER
A panda bear and a baboon are walking toward each other. The panda starts at the
position x = 20 m and walks with a velocity of -1 m/s. The baboon starts at x = -10 m and
walks with a velocity of 1 m/s.
Draw a graph to predict when andwhere they will meet.

• To change the questions and answers, just type over the problems…Use the “replace” feature to change the categories easily
• The daily doubles were originally set to category #4 for $500 and category #2 for $300
• To change the daily doubles you must– 1. Change the hyperlink for the links on the
main board to go to the appropriate question, therefore bypassing the daily double slide
– 2. Change the hyperlink on the continue button on each daily double slide to go to the new question.
