Question

Carly lives in Scottsdale, AZ and plans to go visit downtown Glendale, AZ. The map with a scale of 2 cm for every 4 km shows the actual distance to be 10 km. What is the scale distance on the map?

Answer 1

5 cm

Explanation:

So the map distance is half the real distance a real distance of 10km must mean a map distance of half the distance so i got 5cm.

Answer 2

Comparing map distance to real distance we get 2cm/4km. That means 1cm = 2km.

So the map distance is half the real distance (well, technically not as one is in cm and the other in km but it’s enough to think this way) and a real distance of 10km must mean a map distance of half that (again ignoring the units) so we get 5cm.
