Final answer:
The map scale closest to 1 centimeter representing 80 kilometers is 1:8,000,000, which is determined by converting kilometers to centimeters.
Step-by-step explanation:
The scale of a map that uses 1 centimeter to represent 80 kilometers is closest to the option (c) 1:8,000,000. To determine the scale, we need to convert kilometers to centimeters.
First, we convert 80 kilometers to meters. There are 1,000 meters in a kilometer, so 80 kilometers is equal to 80,000 meters. Next, we convert meters to centimeters.
Since there are 100 centimeters in a meter, 80,000 meters is equal to 8,000,000 centimeters. So, the scale of 1 centimeter representing 8,000,000 centimeters of actual distance is a ratio of 1:8,000,000.
