Agroup of friends are going to a cottage for the weekend and you look at the road map to see where it is. the scale used is 1 : 250,000 the distance measures 8.5 cm on the map. what is the actual distance? km

21.25 km

Step-by-step explanation:

Hello

The numerical scales (E), are also known as scale reasons, the relationship with the size of the map, or a part of it, with its actual size on the ground. Thus, an E of 1: 10,000 means that one unit on the map is equivalent to 10,000 units on the ground.

in the problem we have  E=1:250000

which means that one centimeter on the map equals 250000 cm in ground

1 cm (map)⇒250000 cm (ground)

using a rule of three

1 cm (map)⇒250000 cm (ground)

8.5 cm (map) =x  cm ( ground)

converting that distance to km

100 cm=1m

1000m=1 km

so

x=21.25 km

have a great day.

the answer is 0.3175 hope that you ^w^

also you might actually want to put this picture up if you want people to solve it luckily i remember this question
