The scale 1 in.:120ft was used to create a 169.3-inch tall model of Alaska's Mount McKinley. Estimate the height of Mount McKinley from the height of the model.

Answer 1

169.3 in ( 120 ft/in) = 20,316 ft

Answer 2

I got the same answer. My teacher sais its wrong

Answer 3

Well, maybe she wants you to estimate in your head or on scrap paper rather than use a calculator
like
170* 100 = 17000
170*20 = 3400
sum = 20,400
