Question

On a scale drawing of 1/2 inch = 3 miles on the drawing how many miles are represented by a line that is 4 1/2 inches long

27 miles

Because if 3 miles = .5 inch —multiply that by 2 and you get 6.
Then multiply 6 (4) = 24
24+3 = 27 miles

27 miles because one inch is 6 miles. 6x4 is 24 plus the half which is 27
