Let us construct a scale 6 long. 2—X6= 16 mmutes to cover 6 mches. Construct the scale by dividing a line 6 inches long into 16 equal parts, each part representing the distance traveled in one minute. Divide the space on the left into 4 equal parts giving the distance traveled in a quarter • of a minute. Problem No. 2Foreign Maps You are given a foreign map, scale, 1 centimeter = 1Kilometer. (a) Required, the R. F. Solution:Simply reduce 1 Kilometer to centimeters, and we have the R. F. 100,000 (6) How many inches to the mile in this scale? Rule: To determine the number of inche
