Tyler has 2 maps of Ohio. The scale on the first map is 1 cm to 10 km. The distance from Cleveland to Cincinnati is 40 cm. The scale on the 2nd map is 1 cm to 50 km. Calculate the distance from Cleveland to Cincinnati on the 2nd map, how many times larger or smaller it is and show your math used to find the distance.
What is the distance is 8 cm which is 5 times smaller because 1 cm represents 50 km instead of 10 km. 1/50 is smaller than 1/10. (math DIVIDE 40 cm by 5 to get 8 cm
