Question

what is the ground distance if the map distance between two places is 10 cm and the scale of the map is 1 cm to 85 km?​

Answer 1

Answer: 850 km

Step-by-step explanation:

The scale 1 cm : 85 km becomes 10 cm : 850 km when we multiply both parts by 10. We do this so that the "1 cm" becomes "10 cm". At this point, we have our answer.

You could also solve it like so

(1 cm)/(85 km) = (10 cm)/(x km)

1/85 = 10/x

1*x = 85*10

x = 850
