Two towns that are 31.5 km apart are 3 cm apart on a map. what is the scale of the map?
1 cm = 9.5 km
2 cm = 21 km
2 cm = 18 km
1 cm = 29.5 km

2 cm = 21 km

Step-by-step explanation:

2 cm = 21 km

This is why

3cm = 31.5 km

3/3 = 31.5/3 (To find out how much 1 cm is equal to)

1 cm = 10.5 km

And since 1 cm = 10.5 km is not there in the options... I tried to find out for 2 cm

So, I multiplied both sides by 2

1 cm = 10.5 km

1 *2 = 10.5 *2

So the answer become 2 cm = 21 km

In the picture, we can see a market in a certain town in Netherlands. We can see that some sort of a trade is going on - people are interacting with merchants, giving them money for the goods they want to buy. It is very similar to today's trading system, where you go and peruse through items of clothing and choose whatever you like, and then buy after interacting with the seller.
