Answer:
10 centimeters represent 633.33 miles
Explanation:
This can be calculated using the rule of three: in which we know that 190 miles are equivalent to 3 centimeters on the map, then, how many miles are equivalent to 10 centimeters on the map. This is:
190 miles ----------------- 3 cm
X ----------------- 10 cm
Where X is the number of miles that are represented on a map by 10 centimeters. Solving for X, we get:

X= 633.33 miles
So, 10 centimeters represent 633.33 miles on a map
