Answer:
21 miles
Step-by-step explanation:
You want the distance represented by 1 cm on a map that uses 20 cm to represent a distance of 420 miles.
The distance represented by 1 cm is 1/20 of the distance represented by 20 cm.
1 cm represents (1/20)(420 mi) = 21 mi
1 cm on the map represents 21 miles.
To find out what 1 cm on the map represents in miles, we divide the scale of the map by the number of centimeters.
To find out what 1 cm on the map represents in miles, we need to calculate the scale of the map. The given information states that the distance between Anaheim, CA and Sacramento, CA is 420 miles and the distance on the map is 20 cm. Therefore, the scale of the map can be calculated as 420 miles / 20 cm = 21 miles/cm.
Now, to find out what 1 cm on the map represents in miles, we divide the scale by the number of centimeters, which gives us: 21 miles/cm / 20 cm = 1.05 miles.
Therefore, 1 cm on the map represents 1.05 miles.
