Each unit on the map represents 5 miles. what is the actual distance from oceanfront to seaside?

Istance squared = (X2 - X1)^2 + (Y2 - Y1)^2 
distance squared = (-2 - 3)^2 + (4 - -2)^2 
distance squared = (-5)^2 + (6)^2 
distance squared = 25 + 36 
distance squared = 61 
Therefore; distance = square root of 61 = 7.8 approximately 
 
since each unit represents 5 miles: 
distance (actual) = 7.8 * 5 = 39 miles
