Answer 2

PART A. Answer: 12.5 cm. Explanation. For every 2 kilometers, there are 5 centimeters. 5 kilometers is 2.5 times more than 2 kilometers. So you multiply 5 centimeters by 2.5 and that is the answer.

PART B Answer: .8 km. Explanation. If you divide 5cm by 2, you get 2.5. So divide 2km by 2.5 and that is how you get .8.
